I just discovered a bit more about the state where a long Power key press does not work. My GTA04 was hot in my pocket even though it should have been suspended. I looked at it and connected over SSH and found that: - it was not suspended - long Power key press did not work - top showed qpe constantly using around 95% CPU. Then: - strace on the qpe PID showed that it was continually reading fd 16, but not getting any data - /proc showed that fd16 was /dev/ttyHS3, i.e. the modem. This is all consistent with other recent occasions when I've noticed high CPU usage, or that the modem has stopped working, and I think also with two other UI symptoms: - scrolling stops being kinetic - when using the keyboard, the pressed key pops up but doesn't pop down again until I press the next key. My guesses: - the recent kernel fix for invalid serial state notifications unfortunately isn't quite right, or isn't a complete fix. - This is also related to recent reports of faster than expected battery drainage.
