ok,

I managed to get it to do it again. Captured the problem on serial console:

--------------------------------------------

end_request: buffer-list destroyed
hda1: bad access: block=12440, count=-8
end_request: I/O error, dev 03:01 (hda), sector 12440
hda1: bad access: block=12448, count=-16
end_request: I/O error, dev 03:01 (hda), sector 12448
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
hda: drive not ready for command
hda: lost interrupt
hda: lost interrupt
hda: lost interrupt
hda: lost interrupt
hda: lost interrupt
hda: lost interrupt <-- they never stop appearing
[..more of the same..]

------------------------------------------

Is this a bug or could it be the hardware's fault? The hardware is new lspci
and hdparm -iv follows (I also have the output of sysrq T+M+P is that would be
useful to anyone just ask, I'd rather save the bandwidth and not send it over
the list):
