I've recently started getting errors like this (this example is from
2.4.20-pre3-ac2):

Jan 9 14:20:48 carthage kernel: hda: dma_timer_expiry: dma status ==
0x61
Jan 9 14:20:48 carthage kernel: hdc: dma_timer_expiry: dma status ==

I have a Promise 20267 PCI IDE controller card on an Epox 8RDA motherboard.
The motherboard is brand new and I never got these kinds of errors with
my previous MSI K7T Turbo board. There are two drives on the card:

hda: WDC WD400BB-00AUA1, ATA DISK drive
hdc: WDC WD400BB-00DEA0, ATA DISK drive

which are both alone on the seperate controllers. I've tried both 2.4
and 2.5 kernels (2.4.20, 2.4.20-ac2, 2.4.20-pre3-ac2, 2.5.[53-55] and
get the same errors.

Does anyone have idea what is causing this? I can offer more information
(.config etc) if necessary.
