Source: linux Followup-For: Bug #989010 X-Debbugs-Cc: pitsior...@outlook.com
Preface: In case I did not mention it above, I had a suspicion that the issue might be related to cpu frequency scaling. 1+ month has passed with 5.15. The blank screen issue appeared a few more times the following days. A couple of days later, I decided to disable cpufrequtils, which set my frequency scheduler to schedutil (from ondemand). And the issue has not happened since then! Then I checked debian wiki, which says that cpufrequtils is replaced in favor of cpupower, so I removed it completely and installed cpupower (linux-cpupower package). However, cpupower in debian does not come with a systemd service and it does not have /etc/default/cpupower so as to set a desired governor. I really need such functionality, because as I have said, I set my governor to powersave from May to September every year and now I have no way to. -- System Information: Debian Release: bookworm/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.15.0-3-amd64 (SMP w/2 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
