How does one interpret the following MCA message?

MCA: Bank 4, Status 0x945a4000d6080a13
MCA: Global Cap 0x0000000000000105, Status 0x0000000000000000
MCA: Vendor "AuthenticAMD", ID 0xf5a, APIC ID 0
MCA: CPU 0 COR BUSLG Responder RD Memory
MCA: Address 0x70c42280
MCA: Bank 4, Status 0x942140012a080813
MCA: Global Cap 0x0000000000000105, Status 0x0000000000000000
MCA: Vendor "AuthenticAMD", ID 0xf5a, APIC ID 1
MCA: CPU 1 COR BUSLG Source RD Memory
MCA: Address 0x1b97ca578

It appears that these messages coincide with a 15 to 30
second period where my USB mouse inexplicably loses a
large number of button clicks, (which is quite noticable
with firefox3).
