Kernel Errors

[Troy Knabe]

I am seeing the following errors in my /var/log/messages, any suggestions on where to start troubleshooting this?  I just upgraded from 2.6.9-42.EL to 2.6.9-55.EL.  I did not see the errors prior to the upgrade.  The server is a Sun x4100 with dual AMD 280 Processors and 8gig of ram.
