This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 4 Prarit Bhargava 2010-07-05 14:23:27 UTC 
This warning points to a bad bios which has set up the mtrr values incorrectly.  The kernel was able to detect the bad setting and fix it.

Maybe FW_BUG is appropriate here ... but this is not a bug.
