This strongly resembles an issue I had on a file server --
I don't have my notes handy, but it had to do with an issue
in which the kernel was interacting badly with a particular
motherboard chipset.
The workaround was to reboot with the "iommu=soft" option
passed to the kernel.
My problem was with an "etch" kernel, and it was my understanding
that newer kernels were not expected to have this problem, so
I may be off-base, but that's my experience.
It sounds like this is at least an easy thing to try -- I really
wish I could find my notes...
