Hi,
I'm getting sporadic crashes on my Linux Athena laptop and I'm not sure
whether this is a hardware problem or a software problem. I'd like some
help in figuring out what's wrong so I can determine what I need to do
about it.
I'm including a section from the /var/log/messages file with the error
trace. The setup for this is as follows. The system was running without
the network (run level 4, where the run level has been configured to not
start the network and all the AFS and Athena stuff) at home. I had run
sync and then suspended the laptop. When I brought the system back to MIT,
I woke it up from the suspension and ran a script to reconfigure it for run
level 5, then rebooted.
After the system shutdown and before it came back up I plugged in my pcmcia
network card. This restart did _not_ involve turning off the power. The
system started coming back up and got as far as the AFS cache scan before
it errored. The details of the errors are in the messages log below.
Following the messages quote, I'm including some additional text that
appeared on the console. (This text is a mixture of some of the message
lines and the script output to the consolve.)
The system was responsive to Ctrl-Alt-Delete, and when the system finished
its shutdown -- during the POST -- I turned off the power, waited a bit,
then started it up again. This time it came up without problem.
The problem is inconsistant, but most frequently happens in the situation
I've described above. It has also happened while running, and has occured
about 10 times over the last month.
The hardware involved is an IBM ThinkPad A21m that has been running in this
configuration for over a year. It's running Linux Athena and is up-to-date.
Can anyone provide me with any clues as to what is going on and what I can
do about it?
Thanks,
--Tom
