Dmesg errors/warnings

[Arturo Fermin Jimenez]

Hi all.  I am receiving the warning/errors I list below. Especially 
worrysome the last part which goes on and on.

Could someone point this newbie in the right direction (as in where do I 
start to look)??
BTW I am running FC1 kernel 2.6

Here is the snippet from dmesg:
