Public bug reported:
Hello,
we run several hundred servers with Ubuntu 10.04 as virtualisation nodes
(with about 20-30 virtual machines each) with qemu-kvm 0.12.3 and had to
find out the hard way that some kernel regression was introduced in
linux-image-2.6.32-32-server that made our servers quite instable.
Once every few days they just froze randomly and showed nothing but a
black screen. We then changed back to linux-image-2.6.32-31-server and
got our systems stable again. Unfortunately we were not able to
reproduce this behaviour.
After booting a crashed machine, we found entries like the following in
syslog. Opposed to what it says, I'm quite sure that it's not a hardware
bug, as the same machines just run fine with 2.6.32-31 kernel.
We also tried several upstream kernels from 2.6.36, 2.6.37, 2.6.38 and
even 2.6.39 series - all with the same problem.
