I am not sure which package is at fault; I chose pm-utils just to prime the reporting process.
Background:
Ubuntu 12.04 LTS
Dell Precision M4300
NVIDIA Corporation G86M [Quadro FX 360M] (rev a1)
Everything worked fine until an auto-update a few days ago wiped out the proprietary nvidia code. The system booted first time following the update in a low-res mode (did not check which). I immediately used the GUI option to re-enable the proprietary driver and rebooted. It started without problems and I suspended it after a day of work. The next day, it did not wake up (or maybe it did, but I had no way of knowing that because the screen was blank). When I touched the keyboard, it started flashing caps lock and num lock simultaneously and after a while rebooted itself. The same happened again today.
I cannot see any relevant error messages in any of the logs I know to check.

Still not sure which package is affected; possibly more than one. Another update just came in; the kernel is now linux-image-
In the meantime, the following things happened before the last update:
1. Faled to shut down once. Everything seemed to be normal, the usual shutdown messages went by, the screen went blank and the power light started flashing. I closed the lid and went away. When I came back in a few hours, the machine was hot with the fan blowing full speed, bun not responsive to any inputs. With the lid open, the display light came on showing the remnants of the shutdown message. I did not investigate that event.
2. Attempted to suspend. Everything looked normal and the power did go off. On resume, the system started normally except for black screen with an X11 pointer on it and nothing else. The virtual terminals were working, so I could log in and do stuff. After a long while, the X11 screen came back showing all the windows that were there before suspend and a pop-up saying compiz died (or something to that effect). I have saved the logs for that event. The highlights here are:
Xorg.0.log.old:

There is also nvidia-
Then update came in with a lot of things in it, including compiz. Now when I do suspend I am back where I was when I first reported this problem. On resume, I see a black screen, unresponsive I/O, and caps lock + scroll lock flashing (I have incorrectly reported num lock flashing originally; these were caps lock + num lock in both cases). After flashing for about 20 seconds, the machine automatically rebooted itself. I have saved the logs from aronud this event, too, although I can't see anything interesting in them. Except perhaps this:
