Oops on 2.2.5-15

A server that I'm setting up just oops'd on me. It is running a
freshly installed RedHat 6.0 system. The default RedHat kernel
is running, although I'd prefer a gcc-2.7.2.3 compiled 2.2.10
personally...

Anyways, the system is using a Cyrix 150 CPU running at 120Mhz.
This system previously ran Windows 95 without any frequent
lockups, etc occuring. I am assuming that the Oops that occured
is due to Cyrix chips because the suck so incredibly badly.

The solution is likely to replace the chip with a REAL CPU (AMD),
but I wanted to report the Oops nonetheless in case it isn't CPU
related.

Here is the Oops:

Oops: 0000

Here is /proc/cpuinfo:

[mharris@gw mharris]$ cat /proc/cpuinfo
processor : 0
vendor_id : CyrixInstead
cpu family : 5
model : 2
model name : 6x86 2x Core/Bus Clock
stepping : 7
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu
bogomips : 119.60

Is the problem a Cyrix bug, or a kernel bug? Is it possible to
work around it easily (ie: < 10 minutes work)?

If not, replacing it with an AMD or Intel is likely the cheaper
solution.
