I may not be the right person to answer but I had same problem (same via,
same kernel, same interrupt). It helped when I turned unmasking off, i.e.
try:

hdparm -u0 /dev/hdX  for every X in existing disks you have problems with.

Actually I did some dirty trick too, cause I have UDMA enabled by default
and compiled in via specific settings in kernel config, while at the same
time I set dma off during init, so I do:

hdparm -d0a0u0 /dev/ide/host0/bus0/target0/lun0/disc (or /dev/hda).

I think -u0 is sufficient but you may try the other command too. My
current dirty tricks are overreaction to problems with UDMA few kernels
(and years) ago so the second command is for paranoids.
