Very interesting. The other type of errors I have received (the last time
with 2.4.23-pre4) were:

Ok, so it doesn't sound that the fault is only with Epox mb's.
I sincerely hope that someone with more knowledge about ide-stuff
could figure out something to overcome this particular problem ...
Currently my disk-drivers are made by 2*samsung (SV8004H) and
2*Samsung(SV1604N), in case that changes anything.

BTW. Have you noticed in what situation the lock up happens ?
As all my drivers are mirrored in pairs (ie. Raid1) the system
might run stable for 2-3 days before a lockup unless there is
some heavy transfers going on. In case any of the mirrors required
syncing when bootingg up the system, the system will lockup immediately.

What does /proc/interrupts show in your case ?
Mine is:
/proc/interrupts:

           CPU0
  0:  138788842    IO-APIC-edge  timer
  1:     328481    IO-APIC-edge  keyboard
  2:          0          XT-PIC  cascade
  8:   21357900    IO-APIC-edge  rtc

NMI:          0

And have you tried with ACPI on/off and io-apic on/off ?
