Good morning,

just spotted this MCA event (and subsequently kernel panic):

Oct  1 10:43:42 marvin kernel: MCA: Bank 4, Status 0xf41b210030080a13
Oct  1 10:43:42 marvin kernel: MCA: Global Cap 0x0000000000000105,
Status 0x0000000000000007
Oct  1 10:43:42 marvin kernel: MCA: Vendor "AuthenticAMD", ID 0x40fb2, APIC ID 0
Oct  1 10:43:42 marvin kernel: MCA: CPU 0 UNCOR OVER BUSLG Responder RD Memory

I'd appreciate if somebody helped in interpreting these messages.

Thank you in advance,
Riggs
