Hello

I think I can't boot 2.2.16pre2 (2.2.15 is just fine)
My BP6 motheboard locks during boot process somewhere in the time
the portmap daemon is getting started:

This is what I can see on my console:
(magic key still works, and the seems to be repeatedly written after a
while)

wait_on_bh CPU 1
irq:0 [0,0]
bh: 1 [1,0]

<[c010b560]> <[c010b66d]> .....

according to kernel source this looks like the addresses above
are here:

c010b520 <synchronize_bh>:
c010b520: 83 ec 0c sub $0xc,%esp
c010b523: a1 e0 7a 24 c0 mov 0xc0247ae0,%eax
... skipped ...
c010b551: 75 15 jne c010b568
<synchronize_bh+0x48>
c010b553: 83 c4 f4 add $0xfffffff4,%esp
c010b556: 68 26 02 1c c0 push $0xc01c0226
c010b55b: e8 1c ff ff ff call c010b47c <show>
c010b560: ba ff ff ff ff mov $0xffffffff,%edx
c010b565: 83 c4 10 add $0x10,%esp
c010b568: a1 e0 7a 24 c0 mov 0xc0247ae0,%eax
c010b56d: 85 c0 test %eax,%eax
c010b56f: 75 df jne c010b550
<synchronize_bh+0x30>
c010b571: 83 c4 0c add $0xc,%esp
c010b574: c3 ret

Sometimes this is with CPU 1 sometimes with CPU 0
