[Bug 1087951] Re: mountall 100% cpu ussage

[Steve Langasek]

Ok, I have managed to reproduce this problem (at least partially) by
changing the order of filesystem preferences in /etc/fstab - listing
iso9660,udf instead of udf,iso9660, when the image is indeed iso9660.

/home/ubuntu/raring-desktop-amd64.iso /mnt/starcraft iso9660,udf
user,loop 0 0

In this case, mountall mounts it, then remounts it twice more, then
exits.  So the infinite loop may be related to having multiple loopback
filesystems in /etc/fstab.

Title:
  mountall 100% cpu ussage

Status in “mountall” package in Ubuntu:
  New

Bug description:
  After loging in to KDE I see 100% cpu ussage by mountall. I don't
  konow the exact case, but I suspect AoE or loop devices. Also, it
  doesn't happen on every boot and started several days ago. Previously
  it ocasionaly used to freeze at boot. I'm not 100% sure those two
  issues are related, however since the high cpu ussage started to come
  out I never experienced boot freeze again.
