This looks like a bug in 1.6.2 as well.  Am I reading this right?  If
you end up in trap(), the code in 1.6.2 ends up enabling interrupts
unconditionally, so if you trap somewhere that interrupts are
disabled, you end up with a trip through the trap() with interrupts
enabled when they should not be - causing who knows what.

I'm trying to track down these sorts of problems on my server.
Should I be putting this patch into my 1.6.2 kernel?
