Dear All,

I also encountered the same issue with Ubuntu Server 13.04 while I was trying to checkout all Android projects.

Title:
  Sudden Read-Only Filesystems

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to ubuntu 12.10, I experience sudden locks of my
  filesystems (I have a root and a home partition with ext4), in which
  the filesystems suddenly become mounted readonly. /var/log/syslog
  shows the following entries:

  Oct  7 20:07:57 StudioXPS sudo: pam_ecryptfs: pam_sm_authenticate: /home/lars is already mounted

  The harddrive is one month old and has no defects (AFAIK). The problem
  arises anywhere between directly after boot and 3h into working. A
  remount with mount -o remount,rw is not possible and aborted with an
  error. Since I will most certainly loose data during work, this
  renders my system unusable for the moment. The problem did not occur
  when running 12.04.
