Title:
[Lenovo IdeaPad Flex 14 NoteBook] Full System freeze
Status in linux package in Ubuntu:
Expired
Bug description:
System completely freezes randomly, mostly when running firefox.
without intervention It happens in 2 stages:
1. first it locks everything up, except for my mouse and keyboard.
2. shortly after that the mouse and keyboard lock up and my system freezes.
If i can still use my keyboard in stage 1 and press ctr + alt + F2 I
get these messages in the console:

After switching back to the gui with ctr+alt+F7 the system will again
continue to run normally (I no expert but i looks like it).
Added the full kernlog file
