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/
WORKAROUND: Blacklist sb_edac .

Would it be possible for you to test the latest upstream kernel? Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Please test the latest v3.5kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.
Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text.
If this bug is fixed in the mainline kernel, please add the following tag 'kernel- fixed-upstream' .
If the mainline kernel does not fix this bug, please add the tag: 'kernel- bug-exists- upstream' .
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel- unable- to-test- upstream' .
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".
Thanks in advance.
