Today when I started my computer I got a page fault from irq handler on
bootup sequence:

Aiee, killing interrupt handler
Then was a total hung.
This is the trace:

It never happened before. I use kernel 2.1.121, built with egcs-2.91.57
19980901 (egcs-1.1 release) without any special optimizations.
Feel free to contact me for more other info...
Note: The oops is hand copied, however it was checked twice.
