Rev.1.23 of ata-lowlevel.c broke atapicam on my BP6 system as shown
by the enclosed boot -v messages (the system just hangs, apparently waiting
for a disk interrupt that never arrives; there seems to be no timeout).

The problem seems to be interrupt-related.  rev.1.23 of ata-lowlevel.c
broke things immediately.  Then the new interrupt code mysteriously
fixed them.  Then the next version of the new interrupt code mysteriously
broke them again.  The differences may be related to using apic mode.
I've been testing other things with all possible combinations of SMP
and "device apic" but didn't test all combinations for this bug.  I
mostly just work around the bug by not using rev.1.23.

boot -v messages for a kernel with the bug:

The differences near the end are interesting:
- more "spurious" interrupts for the broken case.  Perhaps they aren't
  spurious.
- ioapic0 routing is apparently incomplete at the point where we get these
  interrupts.  However, using the ioapic and the new interrupt code aren't
  primarily responsible.  The problem also occurs with a non-SMP kernel
  built from kernel sources checked out 1 second after ata-lowlevel.c
  rev.1.23 was committed and that was a few days before the apic was
  available for the non-SMP case.
