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, Srivatsa S.
