Thanks. The bug is simply that the new code doesn't setup the
ioapic for the cases it intends to test. But it does clear out
the original programming. So if the normal good case doesn't work the
code is going to have problems.

Nice to hear, so this is clearly a software setup problem in the BIOS.
Andi do you think you could address this problem?
