current-amd64 page fault trap

[Lars Nordlund <lars.nordlund%hem.utfors.se@localhost>]

Hi

(Perhaps related to the "overnight crash on current-amd64" posted 
yesterday?)

The last couple of weeks I have had problems with my NetBSD-current-amd64.
The computer has been un-wakeable in the morning. Often related to high 
load during the night. CVS updates, pkgsrc-builds or things like that. 
Since I dont have a serial console, use a USB keyboard and always leave 
the computer in X to get the DPMS sleep thingy going.. It is hard to 
reach the debugger.

Anyway, now I know how to reproduce the crash. Or at least produce a 
crash.. While writing a DVDRW and doing heavy disk I/O, the trap may
happen. Here is one I just caught:

(typed from screen..)
kernel: page fault trap, code=0
