Computer absolutely frozen #31

Closed Mato-Z closed 6 years ago

Mato-Z commented 6 years ago

Hello, I have a big problem with system stability after compilation, install and run all components according to https://github.com/Douane/Douane/wiki/Compilation. My computer many times absolutely frozen. Only solution is manually power off (with button) my notebook, so I have to do "hard reset". In my Douane log I see this:

Not only with Skype very often with Mozilla Firefox too.

In my syslog I see:

My system is absolutely unusable. :-( Can you help me please?

I see that it will be very similar as http://blog.zedroot.org/linux-kernel-debuging-using-kdump-and-crash/ so please close this and we can continue in https://github.com/Douane/douane-dkms/issues/26
