Title:
  [Samsung NP530U3C-A0MDE] Panic during boot – 3.8.0-26

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I attached screenshots of the panic.

  on 13.04 during boot, somewhere during starting of /etc/init/ services kernel 3.8.0-19 and 3.8.0-26 panics. I made a quick search but didn't found a related report. Though I found a quick fix in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322
  I installed 3.7.0 as mentioned in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322/comments/23
  to keep on working.

  * Boot never succeeds
  * but sometimes it shows a panic trace
  * sometimes it flickers to black or to frozen mouse pointer like shown in vid.mp4
  * once it showed a panic trace and after some seconds it printed even more screen filling stack trace, and when again even more

  Though I spotted panics with 3.8.0-19, I only did screenshots and
  multiple boots with 3.8.0-26.

  This is new, introduced since do-release-upgrade from 12.10 to 13.04 yesterday. This is an upstream regression as:
  * 3.7.10 works
  * 3.8.0 doesn't
