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

Here is the fresh dmesg output info:

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
Seems okay here:

You sure you haven't upgraded your BIOS or something and forgot to
re-enable HPET?
No it was not upgraded.. Have no option to enable/disable HPET through
BIOS settings though
I was unclear a bit or so. There are no ACPI related settings in my
laptop's BIOS.
Well.. Backout 1.243.2.3 revision of /usr/src/sys/dev/acpica/acpi.c
(committed to RELENG_7 at July 10 by jhb) fixes this issue for me:
acpi_hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff on acpi0
Timecounter "HPET" frequency 14318180 Hz quality 900

dummy(-1000000)
kern.timecounter.hardware: HPET
Hopefully it helps to understand what is went wrong there.
Oleg
