now for a long time. We have moved on to precise or at least to using
the precise kernel (while still keeping the system at lucid) and have
not encountered this error since.

Just to follow up on this.
The 3.3-rc2 ran for almost 2 months without any issues.
We have also re-tested the more recent lucid kernels on a coouple of machines
and as of 2.6.32-38-server #83-Ubuntu, the crashes have not ocurred anymore.
We will give it some more time on more machines, but
Hi Markus,
So does the issue not happen with the officially supported Ubuntu Linux
kernels? Or just the 3.3-rc2 upstream kernel?

We had re-tested the regular Ubuntu kernels. With so many changes since
-32, we may never know, which commit had triggered this and was reverted
or fixed in later versions. It also may or may not have been a Ubuntu

Hi Joseph,
David asked me to follow up on this bug.
Previously we had also tested the oneiric-lts-backports-kernel
(3.0.0-15.26~lucid1-server). This had the same issue, crashing within a day or
two.
We have been running 3.3-rc2 on these four nodes for 13 days now without any
incident. So it
Thanks for you time, Joseph. Since yesterday we are running kernel
3.3-rc2 on four of our nodes for testing - I will report any instability
here.

Would it be possible for you to test the latest upstream kernel? It
will allow additional upstream developers to examine the issue. Refer to
https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.3 kernel[1] (Not a kernel in the daily directory). Once you've

I can repeat a very similar panic at will by running a tiny test program that
just retrieves the manufacturer field of the inserted DVD using a scsi
passthrough command in wine (with either win32 or win64). This is on an

Sigh. Bug 924596 is my bug report with more info about the mcelog I
pasted above. I was distracted in my previous post.

Any applicable workarounds? We tried to force Linux to generate a core dump in
