Kernel 2.6.9-55 issues

[Troy Knabe]

I upgraded from 2.6.9-42 to 2.6.9-55 kernel over the weekend.  I have had issues with 3 servers.  1 server wouldn't boot (x2200 amd 148 proc).  And two x4100's with 2 - Dual Core AMD Opteron(tm) Processor 285.  The two x4100's are spewing these errors, but if I reboot them with the old 2.6.9-42 kernel then I don't get any of them.  Anyone else experiencing issues with the new kernel?
 
thanks
