2.6.9-55.0.2.ELsmp kernel bug?

I have several Sun x4100's with 2 - Dual Core Procs each, running Red Hat 4. When I originally updated to to the '55' version of the kernel, I started seeing these error messages. As soon as I booted off of the '42' kernel, they all went away. Now I updated to '55.0.2' and I am seeing them again. Is this a bug in the kernel? Any suggestions (other than simply go back to the 42 kernel)?

Thanks
