The reason is the value of port 0x61. the difference between 2d and 3d
is almost random (bit 4 changes every memory refresh cycle). The
difference between 2c and 2d (bit 0) is clock 2 enable (the clock used
to drive the speaker). Maybe there was a "beep" at the nmi occured?

Some bioses send some apm interrupts even when it is disabled, so you
might want to compile basic apm support in the kernel. And make sure the
ram is ok. Do you use true parity or ecc ram?

In intel 430tx documentation, there is complete explanation of port 0x61
value. It won't you help much.
