Freeze and reboot with 2.4.0-test12-pre5
Several times now, at seemingly random intervals, my computer has frozen solid. The computer was not under high load--XMMS playing and my typing an email in mutt. X was frozen, the soundcard played the same sound repeatedly, and ctrl+alt+del did nothing. SysRq, however, caused the computer to reboot. Not just SysRq+b, but also SysRq+s. This has happened at least 3 times. The system is a AMD-K6/2 500MHz Model 8, Steeping 12, kernel 2.4.0-test12-pre5+reiserfs, running XFree86 4.0.1
No other useful debug information could be obtained.

Steven,
One question:
Do you have MTRR enabled?
If so, a temporary workaround is to re-compile the kernel with
it disabled.
This is getting to be something of an epidemic.
As I said, AMD's docs state that the write-combining was
altered in the model and stepping stated. However, I would not consider myself *nearly* experienced enough in x86 assembler to start playing around with trying to work up a patch.

To confirm, yes, I do have MTRR's enabled. I'll see if that fixes it... it hasn't happened in the past (checks uptime) 1 day and 9 hours, so
Out of curiosity, has someone found a reliable way of reproducing this?
