[CentOS] Kernel Panic!

Hey all,

Long time user of Centos, I really love what you guys are doing here.  I
have a farm of 50 Centos 4.1 machines. (originally 4.0 updated with yum
up to current 4.1).  Ever since I updated to the 2.6.9-11 kernel I am
getting a lot of kernel panics.  7 machines suffered kernel panics over
the weekend.  Funny that they were the only ones that are booted into
the new kernel!  The rest haven't been rebooted yet so they are still at
the 2.6.9-5 kernel.  They all have similar messages in the logs as show
below.  Any ideas on where to look for the problem?  Has anyone else
seen this?  

Machine info:  Typical of all 50 machines:

P4 3Ghz
2gb ram
U320 SCSI disk w/ lsi scsi controller
Intel Workstation boards
Nvidia graphics

All machines exactly the same, installed w/ kickstart w/ these packages:

@ legacy-software-development
@ editors
@ system-tools
@ base-x
@ gnome-software-development
