Re: kern/45139 (bugs in ACPI(CA) serialization)
Synopsis: bugs in ACPI(CA) serialization
Responsible-Changed-When: Wed, 13 Nov 2019 18:39:55 +0000
Reminder I want to handle this.
from jared: the semaphore code handles this via quickly exiting if (cold || doing_shutdown || acpi_suspended)
To avoid the problem that we might release a lock we don't own, perhaps we can move setting acpi_suspended to 0 to acpi_md_sleep, so it doesn't run with more than 1 CPU. Or use KERNEL_LOCK.
