Ok so the pdc202xx_old hardware flakes out when you have very high
network load (I'd guess in fact very high bus traffic).
The actual log is the disk I/O timing out, then the drive being busy
(probably due to the timeout and a DMA transfer getting stuck). We reset
it and carry on.
Libata happens to log this a lot more visibly than old kernels which is
useful but does mean people sometimes don't notice.
The rest then fits - the freeze I'd expect as we block I/O while trying
to get the drive back.
Doubt the Nvidia module is involved as I'd then expect problems under
high graphical load but you can certainly test that. I don't suppose
you've got a spare PCI network card you could try instead to see if it is
the network card bits ?
