Title:
  [Gigabyte Z87X-D3H] Kernel crash, appears related to ext4 and ecryptfs

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  This problem is very similar, but happened with a different kernel (I
  was using Arch Linux): I am using firefox, I have encrypted my firefox
  profile folder with ecryptfs, and the underlying file system is ext4.
  While I was using firefox, the program became frozen and could not be
  killed. The 'htop' utility indicated that firefox and some other
  processes had status 'D', i.e. 'uninterruptible sleep'. My graphical
  session was still functional, and I could open a terminal and run
  'dmesg', but any attempt to save it to the hard disk would freeze bash
  (uninterruptible sleep, just like firefox). I was able to save the
  output on a different physical hard disk (i.e. not the one that was
  used by firefox and ecrypt). After that I tried to reboot, but this
  caused the kernel to lock up and required a hard reset.

  So far I have not been able to reproduce this issue, so I can only
  give a stack trace for Linux 3.12.6 (from Arch Linux):
