Kernel hangs on Enabling IO-APIC IRQs
 
I'm bringing up this dual core laptop. The kernel hangs with these messages:

Intel machine check architecture supported.
Intel machine check reporting enabled on CPU#1
CPU1: AMD Athlon(tm) 64 X2 Mobile Technology TK-53 stepping 01
Total of 2 processors activated (6834.25 BogoMIPS).
ENABLING IO-APIC IRQs
..TIMER: vector=0x31 apic1=0 pin1=2 apic2=-1 pin2=-1

If I append noapic on kernel options in grub then the machine does
finish booting and I can log in so I'm not at a dead stop but I'd like
to figure out what's going on.

Any ideas where I might look for kernel config options that would effect this?

I haven't found all the stuff I'm looking for in make menuconfig yet
but grepping the kernel config file I've currently got this:

laptop1 linux # cat .config | grep APIC
CONFIG_X86_GOOD_APIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y
laptop1 linux #

I think I really want IO_APICs with a dual processor so I'm wondering
what else might be involved.

Thanks in advance,
Mark
