Public bug reported:

This bug is mentioned in several places and was recently fixed in 10.04
(see #615548
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/615548). Links:

I'm having to run generic kernels on 20 machines currently but have
security concerns with trying to always track "current". Having to
upgrade kernels and reboot far more often is painful as well.

Trying to run the stock kernel results in essentially a DoS steady state
as systems are regularly oops'ing multiple times per day.

Is there any possibility of getting a new stable kernel for 9.10 with
this fix included?

I couldn't actually get a dump on 9.10 because of this bug (that also
has only been fixed in 10.04 and not 9.10):
