I have the same problem, only worse :^<  I could not get through the install
without booting in same mode.  WRITE_DMA errors all over the place when
writing out the superblocks.  I haven't tried the ATA mkIII patches yet, RL
has been very busy & I've not gotten back to this workstation.

It happens all the time for disk activity.  There appears to be no relation
to load or activity.

It's a plain vanilla KT266A system with an 80G WDC PATA drive....

Here is the dmesg info:
