kernel bug in /var/log/messages

[Barry Gamblin]

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.
