Bug Description
[SRU Justification]
[Impact]
Detailed in https:/
some cpu cores offline using cpufreq gadgets or via sysfs may hang the
system.
[Fix]
In v5.16-rc1 commit d6b88ce2eb9d ("ACPI: processor idle: Allow playing
dead in C3 state") fixes this issue.
[Test Case]
As stated in aforementioned bug url, setup cpufreq extention to take
down a few cpu cores, and trigger system suspend. There are ~50% chances
that networking/
sysrq keys.
[Where problems could occur]
According to the patch discussion thread in
https://<email address hidden>/,
the limitation to allow enter_dead in no more than ACPI_STATE_C2 might
not have a practical meaning, but simply C2 was the deepest supported
then.
[Other Info]
While this is currently only available in v5.16-rc1 and affects AMD
Cezanne/Barcelo, oem-5.14/impish and jammy are nominated.
========== original bug report ==========
https:/
Reproduce steps:
1. Install cpufeq gnome extension (https:/
2. Click on the cpu freq extention in the top bar
3. Slide the "cores online" from 16 to 3
4. close lid of laptop
Expected result: the laptop goes into suspend
Actual result: the laptop stay on but screen is now always black and keyboard input is ignored
Fix committed to v5.16-rc1: https:/
