Freeze/Lockup bug in paging request kernel-smp-2.6.18-1.2189.fc5



On a Dell Latitude D820, I've been running the  updates-testing
kernel-2.6.18-1.2189.fc5, usually without trouble.

Today I launched a yum update and the download stopped in the middle
of a package, and the screen stopped being updated, and after a few
mouse clicks, the system locked up entirely. Video stayed on, frozen.
Since this has only happened once, I don't know if it is the kind of
thing to ignore or report in bugzilla. Can you advise me?

Here's what /var/log/messages says:
