kernel oops with dpkg

[Rkimber]

I'm running Dapper flight 6 + updates on an MSI K8T Master2-FAR 2GB

There seems to have been an oops during today's update:-

The oops is a bit hard to read because of launchpad's wrapping - if it it had been uploaded as a text attachment using the add attachment link at the left this would have been better.

I could be wrong but it looks like the crash was while the kernel was syncing buffers to disk?

[Rkimber (rkimber)]

I have the attached oopses since

[Rkimber (rkimber)]

I've never seen this before:-

Badness in unqueue_me at kernel/futex.c:604

full output is attached

[Rkimber (rkimber)]

update crashed

[Chuck Short (zulcss)]

Have you tried running some hardware diagnostics on your machine?

[Rkimber (rkimber)]

Yes. memtest (though not run since experiencing these particular problems, but run fairly recently) has shown nothing. Smartmontools shows nothing. The machine had a new power supply last summer and runs off an UPS.

[Jeff Mahoney (jeffm-jeffreymahoney)]

Your oopses show the kernel has been tainted by loading proprietary modules. Can you reproduce without the nvidia module loaded?

[Rkimber (rkimber)]

I've been away. I'll look at this again when I've caught up with things.

[Grave (blutkind)]

I can confirm same bug, reproduced, only thing we have in common is the nvidia driver (which i removed rmmod) and VIA chipsets.

[Gareth Fitzworthington (mapping-gp-deactivatedaccount)]

This bug has had no activity for a considerable period. This is a check to see if there is still interest in investigating this bug report.

[Rkimber (rkimber)]

It's very old. I'm now using 7.10 on different hardware.

Closing.
