[Bug 573773] Re: ext4 slow mounting at boot

[Mike Yates]

apport information

** Tags added: apport-collected

** Description changed:

  While 2.6.31-21 booted just fine (with exactly the same arguments etc)
  2.6.32-21 froze every time, usually after starting Busybox but before offering a rescue shell.
  It has been cured by moving the rootfs line to the very top of /etc/fstab
  (I had previously sorted my many test drives and partitions in physical order, / = /dev/sdb5, ext4)
  
  Among the many messages briefly (another bug) visible at boot, was "slow mounting, try bootdelay".
  Others were "failed to mount dev on /root/dev" (also proc and sys) which is perhaps mistyped?
  
  In this event, surely, a total lockup should not occur and constitutes a bug.
  Also, the kernel boot messages could be designed to be more informative.
