Your BMDMA controller is reporting raised interrupt (0x4) and your drive
is saying that it's ready for the next command, yet interrupt handler of
sata_via hasn't run and thus the timeout. It looks like some kind of
IRQ routing problem to me although I have no idea how the problem
doesn't affect the boot process.

Can you try to boot with boot parameter pci=noacpi?
