Hi group,
We are getting very frequent Kernel Oops on many machine. The machines have IB104+; PC104 based computer with Transmeta Crusoe TM5800 processor. Almost all the errors seem to be with virtual memory. Here is the output of ksymoops and related information from a machine.

[root@Tioga2 guard]# dmesg | ksymoops --system-map=/boot/System.map
ksymoops 2.4.9 on i686 2.4.20-6crusoe. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-6crusoe/ (default)
-m /boot/System.map (specified)

e100: selftest OK.

There are also times when machines just hang (no oops ). It is possible that hardware is the culprit here (and I strongly suspect it is), but I am not really sure how to confirm that or if it is the kernel or something else. These errors are very frequent on few particular machines. Greatly appreciate you input and time. Thanks

MSR
