There aren't any debug options that need to be enabled. The reason I'm
asking is because we had a bunch of similar issues being reported earlier
that got fixed and it's been calm for a while. That's why it would be
interesting to know if 2.6.35 or 2.6.36-rc2 (if it's not too unstable to
test) fixes things.
Oki, I have installed 2.6.35 now (found backport from ubuntu 10.10 for
10.04), just need to do a reboot at some convenient time.
I just rebooted and ran a similar load of network+disk load that made the
machine give "swapper allocation failure" messages before, and I couldn't
reproduce it with 2.6.35:
2.6.35-19-generic #25~lucid1-Ubuntu SMP Wed Aug 25 03:50:05 UTC 2010 x86_64 GNU/Linux
Doing "sync" in the middle made sync take more than 5+ minutes to complete
(2 hung-task messages in dmesg), but at least nothing ran out of memory.
Considering the amount of people running 2.6.32 and who will be running it
in the future, it still worries me that this is present in 2.6.32 (and
earlier kernels as well).
