NetBSD beast 6.99.6 NetBSD 6.99.6 (LOCKDEBUG) #54: Sat Jun 2 17:32:26 EST 2012 build@beast:/usr/src/sys/arch/i386/compile/obj/LOCKDEBUG i386
>Description:
I have a laptop with built in bluetooth. I seldom turn off my computer or I would have found this earlier.
Bluetooth is supported via ubt and is attached to uhci.
I power down via acpi which works great in NetBSD 5.0.1 but not in current and I assume NetBSD 6.
When shutting down the screen stays on (nothing written on the screen) and I have to shutdown by holding down the power button.
If i disabled bluetooth before shutting down it worked.
>How-To-Repeat:
I don't know if this is reproducible by anyone else it maybe a BIOS/acpi controller problem.
Try to poweroff (ACPI) on a computer with embedded bluetooth supported by ubt(4).
>Fix:
To fix the problem I patched ubt to detach at shutdown I am unaware if this was the default behavior in NetBSD 5.0.

Now shutdown and poweroff work as before, but sysctl -w hw.acpi.sleep.state=5 does not and it didn't work in NetBSD 5 unless I called pmf_system_shutdown first but this is probably not related.

Nat.
