Sorry, i don't seem this can be related. I experienced *no* DMA problems
at all under ubuntu. Just a freeze which generate corrupted data.

please run smartctl tests (package "smartmontools") to see if your disk
is healthy.

regards,

Olivier

I push the on/off button for five seconds, switch the system back on, second boot always seems to be succesful. In the syslog file I see, for the first (failed) boot:
> hda: dma_intr: status=0xd0 { Busy }
> hda: DMA disabled
> The same for hdb. For the succesfull boot, I still have messages:
