No problem,
Tried -CURRENT (from yesterday), esp. src/sys/dev/acpica/acpi_timer.c,v 1.9
If I boot without
debug.acpi.disable="timer"
clock and rtc interrupts run at half the normal rate (50 clock/64 rtc instead
of 100/128) with all the usual results:
- System time (via gettimeofday()) runs at double rate
- Tons of calcru: negative time of ...
- Even more of microuptime() went backwards
- negative running time of some processes if cpu bound processes are run at
the same time.
I have to set
set debug.acpi.disable="timer"
during bootup to get normal running clock interrupts.

Ok, output of "pciconf -lv" attached.
