2.5.74-mm1 dies very early during bootup due to some APIC trouble:
(written down by hand)
Posix conformance testing by UNIFIX
enabled Extint on cpu #0
ESR before enabling vector 00000000
ESR after enabling vector 00000000
Enabling IP-APIC IRQs
BIOS bug, IO-APIC #0 ID2 is already used!...
kernel panic: Max APIC ID exceeded!

Here is the corresponding log for 2.5.73mm3
(pasted from dmesg)

Seems the kernel wants to use APIC ID2, but
2.5.74 claims the BIOS used it up?
