I tried to reproduce the issue as well with the reproducer generated by
syzbot. But what syzbot reported was that the CPU didn't sleep for 140
seconds. But with a long write() we'll go to sleep in between frames. So
when I tried the lockup detector never triggered.

Were you able to reproduce the same CPU lockup as syzbot?
