Upgrade to RHEL 6.2 kernel-2.6.32-220.7.1.el6.x86_64 causes kernel panic on boot

Running RHEL 6 on a new, vanilla Dell T1600 workstation. Nothing attached but keyboard and monitor. Latest Dell BIOS (A10).

Installed RHEL from distribution DVDs; no problems. Then did a "yum update"; no other changes, no other downloads. System now panics immediately on booting with the yum-supplied kernel-2..6.32-220.7.1.el6.x86_64 and is immediately unresponsive to any keyboard input - have to power off to restart.

Last few lines of the trace/dump on the console are below - I can't see any more than this and as a newbie, not sure how to direct the crash output somewhere else (file, COMx, etc) to see it all. Suggestions welcomed....

Superficially this is similar to the output described in https://bugzilla.redhat.com/show_bug.cgi?id=770228 - but since that was only a warning message, not a crash, I'm not sure it applies here. (I have tried "pcie_aspm=off" as mentioned in other postings as a possible solution - no joy.)

Again, suggestions welcomed. I can run on the stock kernel (2.6.32-71.el6.x86_64) for now but would rather be up-to-date.
