Probably not a useful question, but is it at the rate of 1/2 second per
blink?

If you look at the /usr/src/linux/kernel/panic.c file, you'll see that
something failed and called the panic_blink() function.  It's a function
that never stops.  The panic_blink() function is actually defined in
/usr/src/linux/drivers/char/pc_keyb.c and it just alternates the mode of
the 0x01 and 0x04 bits, which are Scroll Lock and Caps Lock
respectively.

Now what called that is quite possibly something that is going to be a
lot more difficult to find out.  Try passing 'noapic noacpi nodma
ide0=nodma nomce acpi=off pci=biosirq' and see if _something_ happens.

Basically the linux kernel has a VERY big problem with your motherboard.
