-Subject: [PATCH] Revert "mailbox: avoid timer start from callback"
-
-This reverts commit 6dc15642c8b830d384fd3e6c9ea63144202b8932.
-
-The Pi 400 shutdown/poweroff mechanism relies on being able to set
-a GPIO on the expander in the pm_power_off handler, something that
-requires two mailbox calls - GET_GPIO_STATE and SET_GPIO_STATE. A
-recent kernel change introduces a reasonable possibility that the
-GET call doesn't completes, and bisecting led to a commit from
-October that changes the timer usage of the mailbox.
-
-My theory is that there is a race condition in the new code that breaks
-the poll timer, but that it normally goes unnoticed because subsequent
-mailbox activity wakes it up again. The power-off mailbox calls happen
-at a time when other subsystems have been shut down, so if one of them
-fails then there is nothing to allow it to recover.
-
-Revert 6dc15642 as (at least) a workaround.
