Reading USB flash during boot issues

[Brent Gardner]

I have several devices that run Bering-uClibc v3.0-Beta2.  These devices
boot from CD and read and save config on USB flash drive.

I'm trying to upgrade to v3.1.1-Beta2 but having a bit of trouble with
the flash drive.

On my test machine and on 2 other machines the setup works as expected,
but on the target machine, the machine does not see the flash drive
during boot so packages and config are not loaded.  But after booting, I
can mount and access the flash drive, no problem.

I'm using the same CD and flash drive on the test machines and the
target machine.  I've also tried burning a new CD and using other flash
drives.  The target machine works fine with v3.0-Beta2.

I've been digging through the logs, comparing logs between the machines
that work and the one that doesn't, I can't find any obvious issues.
I've tried switching around the module load order in initrd.


Can anyone give me other ideas to consider?

Sorry, I was looking at the wrong logs earlier.

I see lines such as these when the machine boots without reading the
flash drive properly:

usb.c: USB device not accepting new address=3 (error=-110)
usb.c: USB device not accepting new address=4 (error=-110)


I'll be researching this but if anyone has an idea I'd love to hear it.

Please have a look if you load additional usb modules in /etc/modules,

these might be missing in the usb_initrd package. Look at your logs and
use lsmod to see what modules are loaded. I suspect you have different
usb hardware in your target machine.

Looking at the initrd the following modules are loaded for usb
usbcore.o
usb-storage.o
usb-uhci.o

along with

scsi_mod.o
sd_mod.o

Thanks for your reply, Erich.

I've been successfully booting the target machine from a Bering-uClibc
v3.0-Beta2 CD and reading/writing config to USB flash for 2+ years and
it continues to boot properly with that config.

Yes, but this is a different kernel with a different initrd.

It is not the isolinux which gives trouble, unless the initrd is
_not_loaded, can you confirm that?

You got many more modules than I found on the initrd, this is
suspicious. Ahhhh.... you are using the initrd_ide_cd

This is the content of the modules directory in initrd_ide_cd

luna:/mnt/boot/lib/modules # ls -l
total 270
drwxr-xr-x  2 root root    288 2009-04-29 22:55 .
drwxr-xr-x  3 root root     96 2009-04-29 22:55 ..
-rw-r--r--  1 root root  37512 2009-04-29 22:55 cdrom.o
-rw-r--r--  1 root root  36628 2009-04-29 22:55 ide-cd.o
-rw-r--r--  1 root root 135908 2009-04-29 22:55 ide-core.o
-rw-r--r--  1 root root   1071 2009-04-29 22:55 ide-detect.o

-rw-r--r--  1 root root  13930 2009-04-29 22:55 vfat.o

so not a single usb module, you are not using the original initrd_ide_cd

And this is also different from the original.

obviously the usb modules are _not_ loaded here

So you are using the usb-uhci just like on the other disk.I am wondering
which modules you use to build your initrd file. You must have the usb
modules included with the ide_cd stuff.

Please run an lsmod on a machine where you can get it to boot and look
for usb modules. Try to determine _when_ they are loaded.
Use an original initrd_ide_cd to build a bootable CD for your target
machine. This will not yet allow you to use the usb stick, but you can
work from there. Load the usb modules manually to determine if they are
working correctly.

If you have a working LINUX system you can gunzip the initrd and loop
mount it, then inspect the contents. You can also add additional modules
as fit, unmount and gzip it to use it on the target.

cheers

Yeah, pretty sure initrd is loaded, otherwise it wouldn't be able to
access the CD to load packages listed in LRP= above.

Right.  Actually, I add the modules and config info from initrd_usb to
initrd_ide_cd and call it initrd_ide_cd_usb.lrp on my CDs.

Finally found the problem.  I needed to increase the usb_wait value in
/var/lib/lrpkg/root.linuxrc in my initrd package.  Default value is 1, I
increased that to 3.  Works as expected now.

I remember (now) having to do this when I first set up my v3.0-Beta2
disks.  Guess I didn't take good enough notes back then.

The machines I'm running LEAF on here are way overkill for the job, so
they run through the boot process too fast to allow for proper USB
initialization, I guess.


Thanks again.

Yes, I saw similar problems with pcmcia based stuff, I would suggest to
increase the default and/or make it a boot parameter.

cheers
