Subject: kernel suddenly fails to boot

I'm talking about kernel 2.6.27, but I also tried 2.6.27.6.
The stunning thing is that the kernel USED to work until right about
now. I last booted Linux on this box yesterday evening. I have had
intermittend boot problems, but they always go away after a reset or two.
The box would freeze at boot at a message about ACPI. Since it usually
went away after a reset, and the box is stable once it boots, I never
really cared enough to fix it.

This is a Core 2 Duo on an Abit IP35 mainboard. The kernel is a 64-bit
kernel.

The very last line before the current freeze is:

TIMER: vector=0x30 acpi1=0 pin1=2 apic2=-1 pin2=-1

I googled this line and found people suggesting "nolapic_timer",
"noapic" or "nolapic". None of these work. This is a 64-bit SMP
system. I also tried "noacpi". All of these get a little farther, but
still freeze the kernel before it even starts looking for SATA devices.

Windows (32-bit XP) still works on the box.

Any ideas what I could do now?

I tried updating the BIOS after this problem hit, but the BIOS update
utility said I already have the latest BIOS.

I have four gigs of RAM in the box, Windows XP only uses 3.25 of those.
Could this be a problem on the remaining RAM?

I also tried "memtest=1", which paused a little but then booted the same
kernel and also froze just the same.

This is not a problem with the RAM, a 32-bit OS will only see that
amount of RAM maximum. (Although PAE will let it see more, IIRC. Could
be wrong though.)

He said he is using a 64-bit kernel.
