One of remote systems got this panic.
Unfortunately, all I have is this bit of its console log.
No crash dump (not even a text dump).
It's curious that va == pte.

Sorry for the false alarm - this was a local environment problem.

Hello,
I experienced this panic few hours ago, but couldn't debug it back
then (the kernel that crashed has no debugging stuff). So here's the
only info I could read from the screen when the box hardlocked:
TPTE at 0xbfefeffc IS ZERO @ VA bfbff000

Hi,
A method to crash current is the following:
cd /usr/ports/editors/openoffice
make extract# does use about 500M diskspace
rm -rfd work# removes everything
make# create it again
I had more panics
I got the following panic while building X with today's current:
