[K12OSN] k12ltsp 4.2.0 smp crash after yum update

[mrok12osn at eastgranby.k12.ct.us]

We just received a new Dell PowerEdge 2800 with two processors.  I
installed Fedora 3 onto it from the k12ltsp 4.2.0 CD's to build a squid
system and all worked well.  I then did a yum update and reboot.  I am
using the graphical interface on the console(level 5).  Very quickly after
I log in, the system crashes with the 2.6.10-1.770_FC3smp kernel.  It does
not crash with the non smp kernel.

I reinstalled from the CD's again and did a selective yum update, adding
everything except the updates that begin with xorg-x11.  Now the server no
longer crashes with the smp kernel.

This server uses a Radeon 7000 video chip and when I google, there seem to
be lots of references to smp problems, but earlier in fedora 3
development.   What can I do to resolve the problem?

Also, I noticed that when using the 2.6.10-1.770_FC3 kernel, either smp or
non smp, the time is set 4 hour earlier than the hardware time on this
server.  I can reset the time after boot up, but when I reboot again, the
time is incorrect.  This does not occur with the 2.6.9-1.681_FC3 kernels. 
Help?
