I'm having similar problems, however mine are spurrious. They happen
maybe 1 in 15 or so reboots. I'm seeing them on two kinds of
machines, both alpha & i386. All the machines I'm seeing this on
have serial consoles, but since about 95% of the machines I take care
of do, they might not mean anything. I haven't seen it on a SCSI
machine, but I'm not sure if that means anything either, since nearly
all our machines boot from IDE disks.
When they happen, the machine is unresponsive. It will ignore
attempts to break into ddb. I'd have tried to debug it already, but
its pretty damned hard to catch. Usually it only seems to happen when
I reboot a machine from home & cannot walk up & hit the reset button.
