[Tor Klingberg]

This is pretty likely to be a duplicate, but I couldn't decide of which one.

It happened when resuming from suspend with an external monitor connected when I was trying my monitor detection scripts using xrandr. Something was loading the CPU 100% and the system was almost completely unresponsive.

Hi Tor,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Typically you'll see something similar to "PM: resume devices took 8.664 seconds" in your dmesg output when this happens. I'm setting this to traiged for further investigation. Thanks!

[Tor Klingberg (tor-klingberg)]

Ok, that makes sense. There are several entries around 3-4 seconds in dmesg, so it probably exceeds 5 seconds occasionally. I have a script at /etc/pm/sleep.d/11vgadetect that detects and enables an external screen on resume. Perhaps that is the culprit.
