I have had the same problem. Only with the 2.2.13 kernel, though I havn't
extesively used older kernels on this particular machine. It is a dual
celeron overclocked to 550 each with 128 MB ram, and the lock ups occur
when the system isn't being used, ususally overnight. I am waiting to
complete my old system so that I can telnet into the SMP box and see if it
is the Xserver locking up or the entire system.
Have you tried to telnet into the machine when it is hung, can you ping
it, etc. Also is this happening in X, I thought my problem had to do with
X and my old video card, I just upgraded to a Voodoo3 yesterday so maybe
that will fix it if it was X. Are you using a brand new video card? (kind
of a wierd problem if it is the video card.) Let me know if you find
anything out please?
