MCA messages in dmesg

Thu Sep 30 06:49:27 UTC 2010

For awhile now, my home server has been acting up.  Actually it had a bad
set of RAM long ago, replaced and it and worked fine.  It's been weird again
now, and I've found this in dmesg:

MCA: Bank 0, Status 0xf200000000000800
MCA: Global Cap 0x0000000000000806, Status 0x0000000000000000
MCA: Vendor "GenuineIntel", ID 0x6fb, APIC ID 2
MCA: CPU 2 UNCOR PCC OVER BUSL0 Source ERR Memory
MCA: Bank 0, Status 0xf200000000000800
MCA: Global Cap 0x0000000000000806, Status 0x0000000000000000
MCA: Vendor "GenuineIntel", ID 0x6fb, APIC ID 3
MCA: CPU 3 UNCOR PCC OVER BUSL0 Source ERR Memory

I really don't know what MCA is, but that looks like possibility bad RAM
again.  I have some other DIMM's I can try, but I was hoping someone had
some info on exactly what those messages mean.  One concern is the
motherboard bad, and hosing the memory.

Some more info:
