I got the following scary error in my logs today when using the ALI 15x3 DMA
support in 2.4.0-test1:
Jun 12 12:20:45 homebase kernel: hda: timeout waiting for DMA
Jun 12 12:20:45 homebase kernel: ide_dmaproc: chipset supported ide_dma_timeout
func only: 14
Jun 12 12:20:45 homebase kernel: hda: irq timeout: status=0x58
{ DriveReady Seek Complete DataRequest }
Jun 12 12:20:45 homebase kernel: hda: status timeout: status=0xd0 { Busy }
Jun 12 12:20:45 homebase kernel: hda: DMA disabled
Jun 12 12:20:45 homebase kernel: hda: drive not ready for command
Jun 12 12:20:45 homebase kernel: ide0: reset: success
According to proc, my hda is a FUJITSU MPD3084AT.
My chipset is an ALI M1543C A1, which proc reports as running at 33Mhz.
This happened out of the blue. The load wasn't extremely high.. I have seen
random hda resets before, but never a DMA message like this. I'm not using the
WDC DANGEROUS option either..
I'll be happy to provide any more info if it might be helpful.
