Based on the comment by Ilia Mirkin in Vincent's bug, I tested the current mainline (4.2.0-rc2) using Ubuntu's config (more or less following the procedure here https://wiki.ubuntu.com/KernelTeam/GitKernelBuild ).

I xscreensaver-command -lock, then logged back in (no issue there), then I xscreensaver-command -lock again and the computer just locked up. Caps lock light was unresponsive on the keyboard, Ctrl+Alt+Delete didn't work, RESIUB magic keys either.

After hard rebooting the computer, here is what what in kern.log and syslog:
