Title:
12.04 kernel hangs during boot (loading sb_edac) on 4-socket Sandy
Bridge
Status in “linux” package in Ubuntu:
Invalid
Bug description:
I was lucky enough to get a 4-socket Sandy Bridge (Xeon E5-4600
series) box, but unfortunately the default install of 12.04 hangs
during boot while loading the sb_edac module. This is due to a bug in
drivers/edac/sb_edac.c, as of now not yet fixed in upstream. However
I sent the small fix: https://lkml.org/lkml/2012/5/31/371
WORKAROUND: Blacklist sb_edac .
