From: Aravind Gopalakrishnan <[email protected]> For Fam17h, we want to report errors that persist across reboots. Error persistence is dependent on HW and no BIOS currently fiddles with values here. So allow reporting of errors upon boot until something goes wrong.
Logging is disabled on older families because BIOS didn't clear the MCA banks after a cold reset.
