Description A. G. 2009-10-21 07:30:10 UTC

My wireless and ethernet networks are dead with the kernel 2.6.31. All work very fine with the 2.6.30 and older. I have a Toshiba laptop wich uses the iwlagn module for wireless and the sky2 for ethernet. I have tested with acpi=off in the grub kernel line but it freezes the system on boot...
ifconfig gets only the lo interface. ifconfig eth0 or wlan0 up gets something like "the interface doesn't exist".

Rafael, this is a 2.6.30->2.6.31 regression.

Given that both the wired and wireless interfaces failed, I'd assume
that something went wrong at the bus level.  Perhaps due to an ACPI
change.

Could the sky2, iwlagn and ACPI developers please take a look, offer an
opinion as to where we should be looking?

Thanks.

This looks like a duplicate of http://bugzilla.kernel.org/show_bug.cgi?id=13940

There's a patch in that bug that is upstream already:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=15b812f1d0a5ca8f5efe7f5882f468af10682ca8

Please try booting 2.6.31 with "pci=use_crs" and report the result.

If possible, please also try booting an upstream kernel containing
the patch above (without "pci=use_crs") and report that result, too.

Ping!  A.G., have you had a chance to try this out?

Comment 4 Luis Chamberlain 2009-11-17 15:55:04 UTC

This seems like a duplicate bug report, any feedback from the user on rc7 would be nice, or at least on 2.6.31.6.

Comment 5 Florian Mickler 2010-12-18 01:09:19 UTC

Chances are, that such a severe issue won't go unnoticed for too long. (It's been a year already...). 

I'm closing this as duplicate as suggested by Bjorn above. 

A.G., please shout if that issue is still prevalent in current kernels.
