Thinkpad x61 Tablet (irq 20: nobody cared)

[Jan Gutter-3]

Hi all,

I've recently acquired a Thinkpad x61 Tablet (model 7767-B8G) and I'm
trying to get Gentoo Stable running on it with varying degrees of
success. I'm medium-to-advanced in getting kernels to work on weird
hardware, plus I'm not afraid to patch the heck out of stuff!

Since this hardware is brand new, I'll try to keep bashing at it till
everything works. I'll split out the different problems in different
mail threads to keep everything sane.

I'll try to get my experiences up at thinkwiki sometime this week
(there's a few patches with ALSA and the wacom tablet that's required,
some hints on how to shrink the EVIL VISTA partition, etc...)

Now to the problem:

I'm running kernel 2.6.22-gentoo-r2 #1 SMP PREEMPT (no acpi or pci
options on cmdline). After a minute or so of uptime I get the following
(and then, predictably, the USB ports on the right side go dead):

irq 20: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #20

I assume it's buggy firmware (quirks that haven't been documented yet).
Here's my /proc/interrupts:
          CPU0       CPU1

Finally, I've attached my dmesg. If other stuff is required (lsmod,
kernel .config, etc.) I'd be happy to provide.

Please use me as a test-bench for your code! If you have anything
unrelated you want me to test (thinkpad-acpi comes to mind), I'd be
happy to oblige.

Have you tried updating the firmware?
I had the same with a X61, and the problem went away after updating
the firmware to the newest version (1.06 in my case).

good luck!

Hmm, sorry

I jusyt looked at my dmesg and I also still have the same issue.
I'm not sure if it actually kills an usb port (as far as I can see,
mine are all working).
I read somewhere that this usually is resolved in a newer kernel
release, so maybe you should try 2.6.23 ?

I've managed to get everything working, excluding suspend/resume and the
multitouch panel (the tablet/stylus functionality works a treat.  The
multitouch stuff does appear to generate data on the port, so I imagine
this is just the C driver not knowing what to do with it.)

I did the ALSA patches, yes.  I found all that was required to get the
wacom working was the relevant setserial.  I discovered the ports and
IRQs by booting Vista and looking in the device manager - thankfully,
they're identical to the X41t's (0x200 IRQ 5).

Snap.  The problem goes away by doing the suggested: adding the irqpoll
option to the kernel's command line.  This seems like an acceptable
workaround, but I am too happy to provide any assistance to anybody who
wants to track down the reason.

Yep, in my case, updated the firmware to:

Version: 7SET18WW (1.04) Release Date: 2007/07/17

I presume the X61 and X61 Tablets have different firmware?

Yah, but you know the drill by now: Linux devs mostly only get their
hands on hardware after release, while hardware vendors think there's no
bugs in the system if Windows boots ;-)

I've got the multitouch (bit of a misnomer, though ;-) working, but the
input is very noisy: i.e. lots of false repeat button-presses, etc. It
seems linuxwacom-0.7.8_p2 can interpret the finger-press events. The
whole X input section is in for a big overhaul, though, so I think the
input methods are going to change soon.

Unfortunately it seems to hang my laptop when I try that. I wonder if it
might be different BIOS settings?

Please DON't do irqpoll!!!!
It'll driver your wired connection crazy.
Basically your e1000 port will continuously loose it's irq address and
consequently it won't work anymore.

As for suspend and hibernate: both seem to work on the X61s. See:
http://hjh.passys.nl/Debian/lenovo-ibm-x61s.html

In the same web folder (actually in the Sid/i386 subfolder), you can
also find alsa packages I build. I currently have sound.

Ah yes, mine is running Debian sid.

I havn't found this.  In fact, I've been delighted with the performance
of both the wired and the wireless controllers.  Both work beautifully.
 Could you provide me with a link to an explanation to what this option
actually does, and why it might have the issues you mention?

Thanks for this.  This appears to have some interesting things for me to
try to resolve my remaining issues.

So far I even have most Thinppad buttons working too (so also wireless
on / off, bluetooth on/off, suspend to ram, sleep and auto suspend to
ram on closing the lid.

The only things I can't seem to get to work at the moment are the
brightness buttons and the volume up/down buttons.

And I'd also REALLY like to have the "page forward/"page back" buttons
to work in the browser, but I have no idea how.

When I went tthrough the buglist, I tried varieous options mentioned

the irqpoll option for me.

Have you tried this:
http://thinkwiki.org/wiki/How_to_get_special_keys_to_work#Firefox
I used the method tinkering with browser.jar Works fine on my T43, but
needs to be redone every time I update firefox. I imagine it'll work
just fine if you find out what is the forward/backward key corresponds
to if F19/F20 doesn't work.

All of these work out of the box for me on Ubuntu 7.04.  I did, however,
patch the thinkpad-keys daemon to only check status once every half
second rather than every 50ms to reduce CPU wakes.  Apparently, in newer
kernels the ibm-acpi stuff renders daemons like thinkpad-keys tpd redundant.

> suspend to ram, sleep and auto suspend to

I only have suspend to RAM working with init=/bin/bash.  I suspect a
module is causing it to fail (it never turns off - it just remains on
blinking the moon LED.)  I have yet to manage to gather the patience to
work out which module it is by removing them one by one and rebooting
everytime.  Suggestions welcome.  (I've tried removing ALSA, the
graphics, and the Wi Fi-related drivers.)

> The only things I can't seem to get to work at the moment are the

My volume buttons work perfectly with thinkpad-keys.  I can change the
brightness manually with poking in /proc.  I suspect configuration
faults somewhere in acpi-support.

They generate keycodes 0xe9 and 0xe0 respectively according to the GNOME
keyboard shortcuts config applet, so they can certainly be detected.
The thing you have to do is make your browser respond to those
keypresses.  I don't believe GNOME or KDE have any infrastructure for
supporting such keys, but perhaps a Firefox extension could be written?

I'm certainly not seeing any of these problems that are mentioned - the
unhandled IRQ appears to only occur once, at boot.  And all of my USB
sockets work regardless of the option being present or not.

tpb is not really developed anymore I think.
The last version dates from 2004.
I do like the osd of tpb though...

Hmm, maybe you could do an "lsmod" and show which modules are loaded?
I'm currently using the ipw3945d daemon, and not the new iwl-wifi driver

"thinkpad-keys"... could you provide a link?

Brightnes does sort of work. There are actually a couple of places
where you can change it a the moment. 2 in /proc and 1 in /sys.
But they don't really carry over well when doing a suspend.
Using xbacklight works like a charm though.
Ah yes, and thinkpad-acpi now "thinks" there are 7 brightness levels
for your screen, while the X61 in fact has 16 brightness levels. So I
guess some work is needed there.

Jiang Qian's solution should work...
Unfortunatly I can't seem to get it running.
I already had keyconfig installed, and I did attach an F# to the keys,
but for some reason The keys don't show up in Iceape/Iceweasel.

I agree; I do see the error just like you, but it doesn't seem to
affect the working of any device on the thinkpad.

The Ubuntu kernels are very modular by default - pretty much everything
is a module.  http://www.rjek.com/x61t-7.04-lsmod.txt has a listing of
what is loaded.

I can't, other than point you at the Debian/Ubuntu source packages.  I
know it is written by one Paul Sladen - perhaps Google will come to the
rescue.

I would avoid the Ubuntu kernels when doing any kind of testing for
suspend/resume fixes. They do not provide an easy way to see what they
have changed from upstream, nor any way to isolate individual patches,
so if it works you have no way to (easily) build your kernel from
that, apply a patch, or submit a bug to your distribution. They don't
seem interested in remedying that situation either, at least last time
I was doing suspend/resume testing.

Please file a bug about it in bugzilla.kernel.org.  This is either a big bad
kernel breakage, or something to make a fuss with Lenovo so that they fix
it.

Hmm, Has anybody checked whether this is still an issue in 2.6.23 ?

Just a first impression (I haven't got the X61 with me now to compare
with my own modules).
But What I noticed is that you've got some extra acpi modules loaded and vesafb.
These are the ones I think are somewhat suspicious:

i915 plus vesafb !!!
tileblit
fbcon (and all related modules)
pci_hotplug
shpchp
mbcache
asus_acpi
sony_acpi
pcc_acpi
tc1100_wmi

Do you know the name of the package?

The additional acpi modules I am assured are harmless, pci_hotplug is
apparently required to support the ultrabase (although I don't have
one), and the framebuffer stuff is apparently loaded by default on
Ubuntu to support the splash screen system.

Yes - I've mentioned it before: acpi-support.

I'm not sure what the combination of vesafb and i915  (both screen
drivers) does. I do know that combinations of these can cause nasty
problems (ATI especially is a problem).
As far as the hotplug stuff goes.  I don't think it should be an
issue, but to try to get suspend to work, starting out with the
smallest number of modules is probably a good idea.

Also, according to Henrique (also on this list and developer of
thinkpad-acpi), loading the smallest number of acpi modules is a good
thing (as in: don't load what you don't specifically need).

Right. I have that one loaded, but I haven't seen the thinkpad keys,
that's why I asked again.
