Dma problems with Promise IDE controller

[Johan Groth]

Hi,
I'm using a Promise controller controlling 4 IDE HD:s, setup as a sw 
raid0 array. Lately I'm getting interuppt problems that looks like this:

Oct 18 18:03:06 lion kernel: hdg: dma_timer_expiry: dma status == 0x61

Well, that is all the info I can think of.
As you can see the system is a:
AMD K6-3 450 MHz with VIA Apollo MVP3 chipset.
Promise Ultra TX02 controller
4 x Western Digital 80 GB ATA100

I thought the controller was dying so I bought a new one but with the 
same result. Can it be that hdg is dying?
