it doesnt boot with ACPI which eliminates first two cases, and I tried all
combinations of
# Workarounds for some known-to-be-broken chipsets (nVidia nForce3-Pro150)
device          atpic                   # 8259A compatability
options         NO_MIXED_MODE           # Don't penalize working chipsets

and none worked... ie. I think it eliminates later two cases


you said the logic of active interrupts is reverted. where in the code can I
revert this? I'll try it and if it works I can define some quirk...

thnx for answer
