Hi
I'm not subscribed to the list, so please cc me at cgalpin@lhsw.com in replies please.
I cannot tell where the problem is occuring. I have a few models compiled after the kernel was built (it's a stock 2.2.5-15 on a Redhat 6.0 AMD K6 II 450 / 256MB), ksymoops couldn't find symbols for. Does it mean one of them is the culprit?
The first happened at 5 in the morning. no much going on then. I was downloading files to a nfs drive (served by this machine) at the time (or shortly before) it dies.
thanks charles
