Subject: ide: disable dma for transcend CF
From: Kirill Smelkov <kirr@xxxxxxxxxx>
I have a CF card which identifies itself as model=TRANSCEND rev=200508011
The card id labeled as TS512MCF80
hdparm -i /dev/hdci reports:
...
DMA modes: mdma0 mdma1 *mdma2
IDE controller:
IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)
but if dma is turned on i get a lot of errors::
hdc: dma_timer_epiry: dma_status == 0x21
hdc: DMA timeout error
hdc: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
...
So blacklist this CF model.
