Kernel errors

[Steven Buehler]

RHEL 5AS
	I have a couple of machines that are getting the following errors in
my log reports each day.  If it was just one machine, I would think the hard
drive was failing, but I am getting these from 2 machines.  If I remember
correctly, I didn't get these errors before putting on the PAE kernels
because I added more memory to each machine.  4 days ago, I upgraded the
kernels again to the latest and still get the same errors.

Any help would be appreciated
