today my linux-2.0.29 kernel crashed, one of the two scsi buses seems to hang
and the adaptec scsi driver emits a lot of abort messages. Login was impossible
so I have to hard reset the machine (ctl-alt-del is disabled as users have
access to the console). (Could a hidden ctl-alt-del be set up ??)
Below is the output of the syslog I found after rebooting.
My Problem is:
What is the stablest kernel for such a machine (pentium 166,adaptec AHA 3940W,
intel eepro100) ?
2.0.30 has crashed the machine approx. 2 times a week, 2.0.29 crashes approx.
every 20 days on friday....
Is there a set of prepatches for 2.0.31 I should give a try ?
Thanks for any suggestions.
Hermann
