Hi,
A change went into 5.17 to allow CPUs to play dead in the C3 state which
fixed freezes on s2idle entry if a CPU is offlined by a user.
This has had some time to bake now, and a regression was identified on an
ancient machine that is now fixed.
Can you please backport these commits to 5.15.y to fix that problem and
avoid the regression?
commit d6b88ce2eb9d2698eb24451eb92c0a1649b17bb1 ("ACPI: processor
idle: Allow playing dead in C3 state")
Now queued up.
commit 0f00b1b00a44bf3b5e905dabfde2d51c490678ad ("ACPI: processor:
idle: fix lockup regression on 32-bit ThinkPad T40").
My apologies; I must have had two references in my tree. The correct hash is bfe55a1f7fd6bfede16078bf04c6250fbca11588
That worked, thanks.
