Warning Message:

is benign
When BIOS hands off control to the Linux OS, BIOS has assigned the conflict region a “write-back” type. However, the X Server process wants to make this type “write-combining.” The OS prints a warning message about this conflict type but does not change it to the new type.
Impacted OS: RHEL AS 4-U3; RHEL AS 4-U4; SLES9-SP3
Impacted Hardware: All server modules (X8400, X8420, X8440)
