frequent oopses on 2.4.20-24.9

[E. Taylor]

On an Acer Power 4100, running Red Hat 9 with a 2.4.20-24.9 kernel,
I get frequent oopses.

It's a 450MHz Pentium 2 with 128MB of memory.  I've run memtest86
successfully.

Here are a couple of examples.

Nov 26 21:39:23 localhost kernel: Page has mapping still set. This is a
serious situation. However if you 
Nov 26 21:39:23 localhost kernel: are using the NVidia binary only module
please report this bug to 
Nov 26 21:39:23 localhost kernel: NVidia and not to the linux kernel
mailinglist.

Any thoughts on what to try?
