Public bug reported:
The bug is as follows:
The whole system freezes except the mouse. After 5 seconds, the screen
turns off as if he put on standby.
After 20 to 30 seconds, in most cases, the screen turns back on and it
is possible to resume the job. But sometimes, the screen comes back but
the rest is still frozen and then the screen turns off again, on again
and so on. In this case, a forced reboot is required.
However, while the system is frozen, magic keys (reisub) are still
functional.
I noticed that this bug occurs mainly when I used my pc so active (file
transfer, web browsing, video playback, etc). I left my pc on for
several days without working on it and according to the system log, the
bug has not manifested.
