DMA timeout error

DMA timeout error

[Adam Sherman]

I have a VIA M6000 board with an ATA CompactFlash adaptor containing a
512MB SanDisk card.

I get the following error during boot:

hdb: dma_timer_expiry: dma status == 0x41
hdb: DMA timeout error
hdb: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest }

hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }

hdb: drive not ready for command
hdb: dma_timer_expiry: dma status == 0x41
hdb: DMA timeout error
hdb: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest }

hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }

hdb: drive not ready for command


Any ideas?

Thanks,

A.

If this is a new CF capable of DMA but CF-to-IDE adapter doesn't support
DMA (most don't) then "ide=nodma" kernel command line parameter should
do the job.  It might be also bug in via82cxxx host driver.

Maybe DMA should be off by default for CF but it requires fixing almost
every IDE host driver and why punish good hardware.

This makes quite a bit of sense seeing as it's a SanDisk "Ultra II" card.

Since the hardware is not reachable from here, I can not test it until 
Monday. I'll note my results though.

Thanks,

add pci=noapic to your boot option
;)
