Yeah, this is not really decoding it - I need to address that case of
uncorrectable MCE not being decoded too.
In any case, it is not E383:
MC4_STATUS[Val|Over|UC|EN|MiscV|PCC|UECC|EEC: GART cache table walk encountered
an invalid PTE (0x05)|ET: TLB(tt:GEN;ll:LG)]: 0xfa0020000005001b
And those should actually be masked out:
"BIOS is recommended to mask GART table walk errors by setting the bit
in MSRC001_0048 corresponding to F3x40[GartTblWkEn]."
And we disable those but for some reason, it doesn't stick :-)
Do
# modprobe msr
# rdmsr -a 0x00000410
# rdmsr -a 0xc0010048
as root.
Thanks.
