System is running Redhat 7.3 with Kernel 2.4.18-19.7.xsmp on an i686.

It is a dual Xeon Supermicro P4DC6 motherboard. This is the message I
got over the weekend:

Feb 9 04:02:01 cedar-l syslogd 1.4.1: restart.
Feb 9 04:22:46 cedar-l kernel: Page has mapping still set. This is a
serious si
tuation. However if you
Feb 9 04:22:46 cedar-l kernel: are using the NVidia binary only module
please r
eport this bug to
Feb 9 04:22:46 cedar-l kernel: NVidia and not to Red Hat Bugzilla or
the linux
kernel mailinglist.

Today I have experienced several lockups on the system requiring a
reset. I had to re-install this system on Friday due to a system disk
that got corrupted. I upgraded the kernel, modutils and glibc, but
nothing else.
