Hah, I actually managed to get netconsole working. This is the log that fails (v2.6.26):
http://folk.uio.no/vegardno/linux/numa-netconsole.txt
I think this looks really interesting:
[ 0.093562] ExtINT not setup in hardware but reported by MP table [ 0.093854] ENABLING IO-APIC IRQs [ 0.094244] ..TIMER: vector=0x31 apic1=-1 pin1=2 apic2=-1 pin2=0 [ 0.094985] ..MP-BIOS bug: 8254 timer not connected to IO-APIC [ 0.094985] ...trying to set up timer (IRQ0) through the 8259A ... [ 0.094985] ..... (found pin 0) ...<7>APIC error on CPU0: 00(80) [ 0.094985] failed. [ 0.094985] ...trying to set up timer as Virtual Wire IRQ...<7>APIC error on CPU0: 80(80) [ 0.105761] works.
This error would be: 7: Illegal register address
Looks like APIC was misconfigured, which might explain IRQ routing weirdness?
Will try to provide the booting one later. Now zZz...
