Title:
  Scheduled fsck during boot unresponsive and inactive for a very long
  time at 90%, making the system appear to hang

Status in “mountall” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: e2fsprogs

  My ext3 filesystem (originally created by Ubuntu Feisty, with a
  sequence of upgrades since then) has currently been mounted over 30
  times since its last check, thus forcing a fsck on boot. If I skip the
  fsck with the Esc key, everything continues as normal and the boot
  completes. However, if I let fsck run, then:

  - the fsck continues as normal until it reaches 89%
  - the hard drive activity light goes off
  - the hard drive makes a sound it normally only makes at system shutdown (although I don't know for certain, it's probably the noise of the hard drive being turned off altogether)
  - after several minutes, the fsck progress continues to 90%
  - the system then hangs thereafter.

  This happens whether I try to boot normally or in recovery mode; in
  recovery mode, this is what the bottom of the screen looks like when
  it hangs (retyped by hand from the view on screen, so may possibly
  contain typos; some of this information is almost certainly unrelated,
  but I haven't edited the portion of the log in question):

  init: bootchart main process (441) terminated with status 1
  fsck from util-linux-ng 2.16
  udevd[446]: NAME="%k" is superfluous and breaks kernel supplied names, please remove it from /etc/udev/rules.d/60-kqemu.rules:1

  init: bootchart post-stop process (450) terminated with status 1
  os_part has been mounted 35 times without being checked, check forced
  Filesystem checks are in progress (ESC to cancel):
  [######################################################------]

  At this point, pressing ESC to cancel the fsck doesn't work; ESC,
  control-C, and control-backslash do nothing but echo on screen as ^[,
  ^C, ^\ respectively (they likewise do nothing outside recovery mode,
  as the echo's aren't visible). Control-alt-delete does work from this
  state, and causes the system to do a controlled shutdown and reboot;
  but another fsck happens on the resulting reboot.

  Suspiciously, the reboots aborted due to fsck hanging don't appear in
  syslog at all (either that, or they do and I can't find them); only
  the boots where I escaped the automatic fsck are shown.

  Expected behaviour is for the fsck to complete and for the boot
  sequence to continue. This drive has fscked correctly with Karmic
  before; the only potentially relevant change to packages that I can
  remember is when ureadahead was installed by the update manager (I run
  karmic-proposed).

  Although this bug has similar symptoms to bug #387692, I think it's a
  different bug; in that bug, the fsck actually completed and the system
  hung immediately afterwards, whereas in this one, the fsck itself is
  hanging.
