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 .
