Bug Description
ProblemType: KernelOops
DistroRelease: Ubuntu 12.10/Mint13 (when using a 3.5 kernel)
Package: linux-image-
ProcVersionSign
Uname: Linux ubuntu 3.5.0-3-generic #3-Ubuntu SMP Mon Jul 2 16:49:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
This bug happens during the boot process with the Linux kernel 3.5 with the daily build of Ubuntu 12.10 as well as Ubuntu 12.04 based Mint 13 when using a 3.5 kernel from the Ubuntu mainline repo. The most recent version I have tested is the daily build from today 08-Jul-2012 10:32, which still has this issue.
I can only attach lspci -vvnn without sudo, as sudo itself hangs without output of any kind. I tried "ubuntu-bug linux", but it has been running for about 15 minutes without any signs of progress so I can only assume that it won't be of much use either.
I don not believe this bug is related to #979402, #979404, or Bug #981877.
