This is not a -current kernel when we talk about ACPI timecounters,
you want a kernel with this commit in it:
phk 2002/02/25 01:51:18 PST
Modified files:
sys/dev/acpica acpi_timer.c
Log:
Add a new test_counter() function which tries to determine the width of
the inter-value histogram for 2000 samples. If the width is 3 or less
for 10 consequtive samples, we trust the counter to be good, otherwise
we use the *_safe() method. [...]
