Title:
  [Lenovo ThinkPad W520] IO Error during boot

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  System: Lenovo W520
  2 SSDs: INTEL SSDSC2CW240A3 and OCZ-VERTEX2

  Installed 12.10 (64bit) but cannot boot it due to IO Errors:

  --- snip -----
  status: { DRDY }
  failed command: WRITE FPDMA QUEUED
  cmd 61/08:e8:6e:24:b7/00:00:08:00:00/40 tag 29 ncq 4096
  res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)

  ....

  revalidation failed (errno=-5)

  ...

  end_request: I/O error, dev sdb, sector 1824233094

  --- snap ---

  (Sorry, I have to type this from a video I've taken so no guarantee
  for every single byte)

  This happens for both disks if I try to install 12.10 on it.

  11.04 works (in this regard) flawlessly on both disks.
