Title:
  [Lenovo IdeaPad Z580] ubuntu kernel regression - stuck at "initial
  ramdisk"

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Hi, I upgraded my Ubuntu 12.10 after installation (so kernel was upgraded from 3.5.0-17 to 3.5.0-21) and rebooted. 
  Results: Ubuntu cannot boot, it freezes at "initial ramdisk". If I switch to kernel 3.5.0-17 ubuntu boots without problem.
