2.6.20*: PATA DMA timeout, hangs

From: Frank van Maarseveen
Date: Mon Mar 12 2007 - 04:55:20 EST


2.6.19 is ok, 2.6.20.[12] hangs from the moment DMA is turned on (hdparm
-d 1 /dev/hda):

hda: dma_timer_expiry: dma status == 0x20
hda: DMA timeout retry
hda: timeout waiting for DMA
hda: status error: status=0x58 {
DriveReady
SeekComplete
DataRequest
}
