ACPI regression on recent 7.0-STABLE: HPET stops working
It seems to be something was changed with ACPI support on 7.0-STABLE
so my next system upgrade ended with ACPI HPET not working anymore on
my ASUS A9Rp laptop.
Here is the part of /var/log/dmesg.today dated July 13:
FreeBSD 7.0-STABLE #65: Tue Jul 8 22:05:07 EEST 2008
root@rainhaven.theweb.org.ua:/usr/src/sys/i386/compile/oleg2
[..]

acpi_timer0: <32-bit timer at 3.579545MHz> port 0x808-0x80b on acpi0

acpi0

Here is the fresh dmesg output info:

device_attach: acpi_hpet0 attach returned 12
And the part of actual sysctl kern.timecounter output:
kern.timecounter.choice: TSC(800) ACPI-safe(850) i8254(0) dummy(-1000000)
kern.timecounter.hardware: ACPI-safe
