Does anyone have an idea of what the below error is pointing to on my F630 running 5.21?

"Wed Mar 3 09:26:49 EST [rc]: relog syslog UNCORR PROC MCHK 98 pc:fffffc0000482260 cia:0 mm:4090 eia:1820f550 fs:ff00 eis:945000000 isr: 0 pci0:3010106 pci1:4000"

I discovered my system was locked up this morning when I came in. After rebooting i discovered the following error in my messages file.
