Hello Ben,

as requested I tried the above "patch" and had no problem so far. Current
situation is:
(ide2, ide3 are PDC, eth2 is tg3)

           CPU0
  0: 6332048 XT-PIC timer
  1: 14112 XT-PIC keyboard
  2: 0 XT-PIC cascade
  5: 0 XT-PIC EMU10K1
  7: 14950 XT-PIC HiSax
  9: 30600647 XT-PIC ide2, ide3, aic7xxx, aic7xxx, eth0, eth1, eth2
 12: 234451 XT-PIC PS/2 Mouse
 15: 2 XT-PIC ide1
NMI: 0
LOC: 0
ERR: 0
MIS: 0

I would not say this is a rock-solid test case. I will continue to stress the
setup and keep you informed. Anyway it looks stable up to now.

Regards,
Stephan
