Hi ACPI specialists!

	I noticed that CPU cooling doesn't work with testing mav_at_'s
	timers_oneshot*.patch, so I got following results:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
$ sysctl -a | grep cx
hw.acpi.cpu.cx_lowest: C1
dev.cpu.0.cx_supported: C1/3
dev.cpu.0.cx_lowest: C1
dev.cpu.0.cx_usage: 100.00% last 24us
dev.cpu.1.cx_supported: C1/3
dev.cpu.1.cx_lowest: C1
dev.cpu.1.cx_usage: 100.00% last 485us
dev.cpu.2.cx_supported: C1/3
dev.cpu.2.cx_lowest: C1
dev.cpu.2.cx_usage: 100.00% last 155us
dev.cpu.3.cx_supported: C1/3
dev.cpu.3.cx_lowest: C1
dev.cpu.3.cx_usage: 100.00% last 590us
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

	I did enable ACPI debug on /boot/loader.conf like following:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
debug.acpi.layer="ACPI_ALL_DRIVERS"
debug.acpi.level="ACPI_LV_INFO"
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

	I got a result of dmesg, like attached 'dmesg.txt'.
	I researched that sys/dev/acpica/acpi_cpu.c, but I couldn't
	understand what's happen.  I think that CF-R9's ASL has a
	_CRT issue, but I couldn't find it in ASL file:-(.

	What do I do?
