This kernel is seriously busted. Sometime between the Dec 15 tree and
the Dec 31 tree someone added something which appears to be causing
writes to the (ata_piix controlled) disk to get lost. Processes are
getting stuck in D state, usually before it reaches a login prompt.
Suspects would be block, ata, scsi and possibly x86/acpi interrupt
handling.
And no, I'd rather not bisect - it would take ages. If the maintainers
of the relevant trees can suggest specific patches to revert then I can
take a look at that tomorrow.
