Bug description:
  I am on Ubuntu 11.10 64bit and testing Ubuntu12.04 in kvm-qemu0.14.1
  +noroms-0ubuntu6.3 on it.

  On running Ubuntu12.04 in kvm-qemu my Ubuntu 11.10 host kernel throws
  ata exeptions of different kinds.

  One high repeated:

  Mar 26 13:44:07 ubuntu kernel: [ 3941.779080] ata1.00: exception Emask 0x50 SAct 0x1 SErr 0x480800 action 0x6 frozen

  Mar 26 13:44:07 ubuntu kernel: [ 3942.292077] ata1: EH complete

  
  Interestingly the ata entries stopped when I switch of the Ubuntu12.04 guest.

  They may be caused by guest Ubuntu12.04 kernel3.2.x I/O errors which I
  could observe there in.

  I will attachadditional the 12.04 guest logs when and if I get it
  manage to access them.

  Anyway, the host kernel(3.0.x series) should not be affected of guest
  kernel misbehaviour. This me cause in short time a corrupted
  filesystem.
