Description Alan Grow 2007-06-29 00:30:09 UTC 
A -CURRENT build from yesterday panics every time on S3 suspend / resume:

panic: _mtx_lock_sleep: recursed on non_recursive mutex acpi subsystem GPE lock @ ../../../dev/acpica/Osd/OsdSynch.c

Fix: The tip-off is in sys/contrib/dev/acpica/CHANGES.txt: "All interfaces to the global lock now allow the same thread to acquire the lock multiple times." However, mtx_init() is still called without the MTX_RECURSE flag in sys/dev/acpica/Osd/OsdSynch.c. The following patch fixes it for me:

How-To-Repeat: $ acpiconf -s 3
