I am using sys-kernel/gentoo-sources-4.1.12 and occasionally the system is totally freezed - I can't move mouse, nor can I ssh login (network unreachable). after rebooting I can't find any unusual message from /var/log/messages.

all I know about this problem:

- This never happened when I was using sys-kernel/gentoo-sources-4.0.5.

- and the system freeze usually happens when I was watching video in fullscreen mode using firefox, no matter the player was powered by html5 or flash. (I haven't run into any system freeze while using smplayer)

could you give me some clue about what can I do for troubleshotting this: alternative places to look for logs / any idea about what the problem could be / whatever you think might be helpful is appreciated.

Usually a hardware problem: marginal motherboard or bad power supply.
Try different drivers to workaround the problem.
