Subject: How to debug system freeze?
Date: Thu, 23 Feb 2012 20:52:55 +0100 [thread overview]
Message-ID: <4F469917.6050503@gmail.com> (raw)
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?
Thanks,
Lukasz Sowa
