Re: VIA vt8235 headache

[Petr Sebor <petr@scssoft.com>]

Hi,

with this patch applied over the 2.4.21-pre4-ac2, the CDROM on IDE1 now
works ok, no more error messages.

The harddrive on /dev/hdc is still choking though...

hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x00 { }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x00 { }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x00 { }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x00 { }
hdc: DMA disabled
ide1: reset: master: error (0x00?)
hdc: lost interrupt

Regards,
Petr
