Hi,

I'm experiencing strange bug when I close lid of my laptop - system
freezes (no reaction on keys, no response form ssh) hard and displays
some strange colour effects. The kernel log (after reboot) shows
nothing. My question is - how to debug it? Maybe there's a way to track
last called kernel function or something similar?

Maybe you can try the pm_test framework (see Documentation/power/basic-pm-

debugging.txt) to narrow down the problem.

Regards,
