Strange DMA-errors and system hang with Promise 20268

Hi.

The last month or so I've experienced some strangeness with one of my
boxes. It is up and running without any problems and then suddently i
get this in the syslog:

Mar  6 20:29:42 eurisco kernel: hdf: dma_timer_expiry: dma status ==
0x61

(sometimes dma status has been 0x41)

And a few seconds later the system has frozen and I have to reset the
box to get it back up and running.

It isn't always the same hdX. If I remove the device that produces the
error another device, but it's allways a device on the promise
controller, fails.

I've seen this behaviour with 2.4.25, 2.4.24 and 2.4.23 (I think).

Any ideas?
