Hi,

The last 3 days, I'm getting this message on my (i386 based, FreeBSD 8.1 
PRERELEASE) system (frequency about 1 time per day):

MCA: Bank 2, Status 0x940040000000017a
MCA: Global Cap 0x0000000000000104, Status 0x0000000000000000
MCA: Vendor "AuthenticAMD", ID 0x680, APIC ID 0
MCA: CPU 0 COR GCACHE L2 EVICT error
MCA: Address 0x5f4540

I have no clue what it means. Should I be worried?

Thanks,

Frank
