It's not that easy. The problem occurs only when I'm going to suspend with closing laptop's lid and it does not happen every time (but mostly yes). I'll try to enable CONFIG_DETECT_SOFTLOCKUP but if it's hard freeze, will I see the output?
not everytime...ok that makes situation harder. Maybe you need serial console and hook another computer to see the kernel log. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
