Description Matthew Booth 2008-03-13 10:49:12 UTC 
Description of problem:
Since upgrading to RHEL 5.2 beta, I get many messages like the following on
every boot:

Timer ISR/0: Time went backwards: delta=-327739297 delta_cpu=16260703 shadow=979

I didn't see this on RHEL 5.1. This is on a Lenovo X60s laptop.

Version-Release number of selected component (if applicable):
2.6.18-84.el5xen
