I have been running for over a month now on the older Hardy kernel (2.6.24-23-generic x86_64) and have not seen this issue at all. So it appears it's almost definitely something broken in the newer kernels. At this point it's unclear if it is an Ubuntu or Linux kernel problem.
With that said, I found this: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=e8c82c2e23e3527e0c9dc195e432c16784d270fa Has anyone tried this simple patch against the Ubuntu kernel?
