Random whole system freezes.

My laptop (Lenovo G50-80 with i5 5200u) randomly freezes, audio starts playing in a short loop, nothing works. I have to manually reboot it. There is nothing in logs (journalctl usually ends 10-20 minutes before freeze).
Someone had the same issue before, it seems like this is somewhat common bug on this cpu. Starting kernel with "intel_idle.max_cstate=1" helps but battery life is so short that I cant really use it without a charger (I'm taking notes on this laptop in school, so battery life is crucail to me).
This happens on official arch lts kernel too. I have tried different kernels from AUR and only old kernels like 4.4lts and 3.16lts are not affected, but they come with different problems.
3.16 is very unstable and often things crash (like xorg ...).
Nothing crashes on 4.4lts but I'm experiencing many graphical problems (screen tearing so bad that I cant use this kernel).

I don't really know what to do at this point. I can use my computer only when it is plugged to a charger.

Tried running debian stable on different drive, it happens there too.

https://bugzilla.kernel.org/show_bug.cg … 9051#c1004 *seems* *claimed* to be an effective workaround as well.

Thanks, I think the last one (#c1004) works. Haven't had any freeze since yesterday.

Edit: Doesn't work, just had freeze ...
