next in thread | raw e-mail | index | archive | help
Hi,
Machine: PII266, 64MB SDRAM, SCSI HD x 2, nothing out of the ordinary
This machine has rebooted twice in the last few days, both times with little
to zero load, both times with no users logged on, once with several Samba
connections active. No messages went to /var/log/messages.
Upon searching the archives I saw a quote from DG about idle state panics
being very suspicious, prob RAM or disk errors... I'm building a debug
kernel tonight and will be able to forward more details as soon as I can.
So, my Q is, any other ideas that people may have in the interim as to what
would cause these panics?
