Hmmm, another panic where the system stays (sort of) up. I had one too,
but I was messing with filesystem code when it happened to me. Very
weird, that a panic would let the system still run. Maybe since it
wasn't in task[0]?
btw,
Anyone know how safe it is to do *anything* after one of these, or
should one go for the reset switch? Judging from the fact that when it
happened to me, I could still create files on unaffacted filesystems,
and syncing worked, then hung (i.e. sync would hang after writing the
disk blocks), and rebooting had the created files still there and the fs
clean, I would sync &, kill -TSTP 1,kill -9 -1,sync and then reboot, and
try to get a fairly clean shutdown.
