I cannot recall having observed any nouveau suspend failures, but that
might have had to do with switching to NVidia proprietary before having
suspended. At least for NVidia suspend worked just fine.

I will soon test Quantal to sort this out.

Title:
  10de:0652 [Samsung NP-R710-AT01NL] Nouveau freezes after
  suspend/resume in Ubuntu 13.04 / 3.8.0

Status in “linux” package in Ubuntu:
  Incomplete
Status in Arch Linux:
  New

Bug description:
  Before updating to Raring yesterday, I first fully disabled the Xorg-
  edgers PPA (by ppa-purge) and was therefore switched back to the
  Nouveau driver. Then updated my system from Quantal to Raring.
  Afterwards, I noticed that after a suspend/resume the greeter would
  not appear or hang completely. I was intermittently able to move the
  cursor, but the GUI would not respond to hovering or clicking.

  I did not experience this bug in Quantal with kernel 3.5, but I rather
  quickly switched to the proprietary driver for performance reasons.

  I am on a laptop with NVidia GeForce 130M video card on Raring with
  kernel 3.8.0, no experimental drivers in use. Attached is also a dmesg
  log from a previous time this occurred, with me trying to recover from
  the situation by various means - there are a lot of nouveau-related
  error messages in it. Ctrl-alt-backspace does nothing, SysRq+K does
  what it is supposed to do but to no avail, restarting lightdm
  obviously does not help.

  To reproduce:
  1. Boot
  2. Suspend
  3. Resume

  Observed behaviour:
  The greeter does not appear or hangs completely, switching to another VT is initially impossible, after a certain period of time nouveau starts spitting out error messages to the screen and it is then again possible to switch to another VT. Sometimes X randomly restarts and shows the boot-time greeter, where I can log in, but after that the system freezes again.
