^^^ 2.6.24 is pretty old in LKML time (we're up to 2.6.29-rc7 in terms
of unstable releases and 2.6.28.7 is the latest stable at the time of
writing) so the issue might have been fixed. Generally if your kernel
isn't the latest stable/unstable and you don't have the facilities to
reproduce the error with a the newer kernels it is best to report the
issue to your kernel vendor (in this case Ubuntu) first as the issue
might have already been fixed. I would strongly urge you to file this
bug in the Ubuntu bug tracker. Details about how to do this can be read
on https://wiki.ubuntu.com/KernelTeamBugPolicies .

There's a mangled BUG message somewhere below (CC'ing Rik).
Unfortunately your email program has line wrapped the log file making it
very hard to read.
