About a week ago my system began to freeze (deadlock, only manual shutdown with laptop button helped) from time to time.
The frequency of deadlock is increasing. Today it was about 10 deadlocks with only browsing the internet and terminal emulator and vim. It usually happens when loading new url and then all the system is dead. It's very annoying for me as it happens more often.
My system is
Lubuntu 11.10 with
xmonad window manager.
Could you help me to find the cause of this problem? Are there some logs associated with deadlocks? Could it be hardware problem?
(the system was dead twice while writing this question too)
