Several oops'es

Hi,
Hope I'm not ticking people by submitting these. I been
getting quite a few hangs where the system becomes locked. Once
I could get in to the system from a remote telnet and recover.
Sometimes I can ping the Linux machine and its responds but I
cannot telnet in. Most of the time I cannot ping from a remote
machine, X is frozen and I have to reboot putting my disks at
risk.
I turned on more debugging messages with klogd and syslogd.
After doing that I got flurries of mem_map disagreses...etc. and
the system freezes increased to occurring every several minutes.
The reason I wanted more messages is I have had freezes every
1-7 days. I just found out an hour ago there is some Cyrix
"Coma" bug where some kernel loop occurs with interrupts
shutoff. So I guess there is no further question about system
freezes. But turning on more messages hosed things to a
standstill. I queried the linux groups for quite a while before
buying 3 Cyrix boards and got nothing but OK's.
Is there any other info on divining oops's. I do have
oops-tracing.txt.
System.map attached.

Motherboard: 8500TVG
CPU: Cyrix 200 i686
Mem: 64meg
OS: Linux RH 5.2 2.0.36
Sys disk: Caviar 1m
Data hdb: Fuji 2.4
Data hdc: Fuji 6m
System is a server (Samba) for masqueraded NT systems connected
to ISP by PPP and does not do much other than have a few xterms
going looking at HOWTO's or monitoring like tcpdump on eth0 and
xosview.
