This is repeatable on x86_64 2.6.27-7 -9 and -11.

this report involves 3 machines: cf67, asus17, averatec

Panic occurred on dv67:

(12:13:24 PM) bwh: Seems like a bug in the forcedeth driver (or hardware)
(12:15:09 PM) bwh: It apparently received a packet 1664 bytes long, but it should be limiting to 1518 bytes by default
(01:04:08 PM) bwh: That oops message shows an 'M' taint flag which means there has been a machine check exception, which normally indicates a hardware fault of some sort

Changed in linux:

I am going to verify it doesn't happen with ath_hal. it may be imposible to run dvswitch app wihtout nvidia, dvswitch needs "Anything that supports Xv (video extension) should work" which vesa seems not to.

00:12.0 VGA compatible controller: nVidia Corporation GeForce 7150M (rev a2)
The opensource xorg nv driver doesn't support that card:
(WW) NV: Ignoring unsupported device 0x10de0531 (GeForce 7150M) at 00@00:12:0

I may be able to get a headless version or something just to try to trigger this bug.

also: /etc/modules is not a good place to load netconsole because eth0 isn't up yet, so it aborts.

I wrote a script to load it and the 2 apps:

sudo modprobe netconsole netconsole="@/,@192.168.1.155/"
dvswitch &
sleep 4
dvsource-firewire

I booted without ath_hal and nividia binaries. same thing:

Comment 3 still shows the taint due to machine check exception. Comment 4 doesn't have that anymore, so that's out of the way.

The first attachment of this bug contains test code (a server and a client). Maybe you can use this to get a test case together for your bug.

I more likely means that nobody is here who knows the driver well enough to suggest a fix. You could report to upstream: <email address hidden>, Cc: Ayaz Abdulla <email address hidden> (forcedeth developer). Upstream will be more interested in reports about untainted kernels though. Vanilla 2.6.29(.1) perhaps.

I read in another bug though that ubuntu devs don't want bugs filed
upstream and instead want them filed with LP:

https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/246843/comments/3

This inconsistency makes it difficult to know when to file upstream and
when not to. What's the point of filing bugs with LP if the suggestion
is only going to be to go file it upstream instead?

b.

I'm not speaking for Canonical, I'm not even using Ubuntu. I'm only watching this bug because I am one of the upstream kernel driver developers (ieee1394; Carl's report was loosely related to 1394).

If there is a possibility that a bug is an upstream bug --- and if your distributor has no manpower to look at bugs and to get in touch with upstream themselves --- then file a report with upstream. Best would be of course if one of you could test an unmodified kernel.org kernel for your report; ideally the latest release*. (Note, reports about kernels with proprietary drivers inserted into them do not have much value for bugzilla.kernel.org because such kernels cannot really be debugged.)

*) Does Ubuntu have packages of vanilla kernels?
