I'm horrified that it has been well over a year between this problem
being reported and the first non-automated response from Ubuntu. Yes,
this problem still exists on Ubuntu 14.10, but I have managed to
implement a workaround. If I disable the Nvidia graphics card in BIOS,
and use the Intel graphics card instead, the problem goes away. This
means that I can't play games on the laptop, but given how appallingly
slow Ubuntu is to respond, I see no point in pursuing this bug report
any further. I'll probably have replaced the laptop before anything is
done about this. As far as I'm concerned, this bug report can be closed.

Title:
  Thinkpad sometimes won't suspend

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I've filed this bug against pm-utils as I'm not sure which package is
  the root cause of this. My apologies if it's really something else.
  Feel free to re-assign in this case.

  I have a Thinkpad T530 running Ubuntu 13.04 that will sometimes
  suspend, but sometimes won't. When it won't, the suspend LED flashes
  for a few seconds, then the battery LED flashes for a seconds, and the
  system returns to normal running. When this happens, no amount of
  trying to suspend seems to work, and the only option is to do a full
  shutdown. Here's the part of /var/log/kern.log that seems most
  appropriate:

  other details that may be of interest:
