15790060 RHEL 6.2 - APEI: Cannot request iomem region <000000007f790800-000000007f790804> for
GARs
Issue::
The following error message of APEI appears in RHEL 6.2 dmesg when the system boots using
default kernel parameters:
APEI: Can not request iomem region <000000007f790800-000000007f790804> for GARs.

Workaround:
Disable ERST of APEI by appending erst_disable to the kernel command line. The following
information will be displayed in dmesg:
