Hi,

I have been having continual problems with recent kernels
(2..4.{18,19,20}) locking up. It usually happens at night when the
machine is idle. Usually the logs are empty. Sys-Rq produces no
response. The only option is a total reset.

It has happened again overnight. Looking in the logs, there is an oops
late yesterday evening, which I hope is the cause and will help this to
get nailed.

K6 200. TX motherboard.

Let me know if you need any more information.

Thanks.

Mark
