r8101 in F12

[Joseph L. Casale]

What's the trick in getting this nic to work for either the beta
dvd or snapshot netinstall iso?

F11 seemed to have support for it?

Thanks,
jlc

Weird. Can you provide output of lspci -v?

Sure,
Here is the output from F11:

(F12 attempts to use the same module (r8169) but its rather non functional...)

Looks like there is no support for 8101 in 2.6.31 kernels, others have
had issues compiling as well:

error: ‘struct net_device’ has no member named ...

I might be skipping F12 on this HP laptop, the external USB ports don't
work and the rpm fusion wl akmod doesn’t work either:(

How do you mean? Can you provide more details?

The module is obviously buildable in the F12 kernel source, or else it
wouldn't exist...there may be a patch in the F12 kernel package to fix
this?

external USB ports don't work on an HP sounds like bug 524808 , which
we're currently evaluating as a blocker:

https://bugzilla.redhat.com/show_bug.cgi?id=524808

if I were a betting man I'd bet you have 3 or 4GB of RAM (or more) and
lots of "nommu_map_single: overflow..." messages in your kernel logs.
Workaround: boot with 'iommu=soft' kernel parameter.

btw, is anyone else on the list suffering in silence with an HP or Acer
system with 2.5GB or more of RAM which either doesn't boot or whose USB
ports don't work? I'm trying to get an accurate evaluation of the level
of impact of this issue. If you are, please try booting with the
'iommu=soft' kernel parameter and if it helps you, PLEASE SAY SO! (also,
comment on bug #524808). Thanks.

Hew Adam,

I just searched the web and found that a few Ubuntu users w/ 2.6.31 kernels
could not build realteks source.

Hrm, how do I look further into this?

Heh, you should bet more often, it's an HP DV6-1030ca w/ 4gig of ram. I
should of searched bz given I also saw that "Broken Bios" message and
chuckled...

I am just putting F11 back on it now (I need it tomorrow all day...) but
I left empty space so I can slap an F12 install on it next week.

Hopefully I figure out how to get the nic working, that makes setting it up
rather hard:)

Thanks!

Would the live cd also produce the issue and allow me to boot with this kernel
param to test?

yes, it should happen on the live CD too. If you're wondering if this
issue could be breaking your network adapter too, it's certainly a
possibility, I don't know enough to say either way. It would be
extremely useful if you could test this, like, ASAP :) we are still
arguing about what to do about this bug. if you could:

a) test that iommu=soft fixes your USB issue
b) if it does, does it fix your network issue too
c) stick around for the next few hours in case we need you to test
anything else

that would be HUGELY helpful. if you have IRC access, it would give you
super-mega-awesome bonus points to hop online to #fedora-devel and/or
#fedora-kernel on freenode and ping me. thanks :)

Well, please ignore the vendor driver, it is crap (it is used as
"documentation" to write the proper driver i.e r8169).

Also can you provide a dmesg output and what do you mean by "nic does
not work" ?

Is it simply not detected or does it refuse to transfer any data?

Adam and dwmw2 got it sorted out with a new kernel build in irc.

thanks,
