Anyone have a e5 sandy bridge.
I keep getting an EDAC sdbridge error.

EDAC sbridge: Some needed devices are missing
EDAC sbridge: Couldn't find mic handler
EDAC sbridge: Couldn't find mci handler

Not sure that my registered ram is initilized.

And the output from lspci

lspci -n | grep 8086:3ca0

lspci -k -s 7f:0e.0

	Subsystem: Super Micro Computer Inc Xeon E5/Core i7 Processor Home Agent
	Kernel modules: sb_edac

And lsmod

lsmod | grep sb_edac

sb_edac                24576  0 
edac_core              49152  1 sb_edac

Any one seen this?
