I just encountered a problem with my PC-engines WRAP board, with funny 
things happening to my systems' time
(thread: )

I have to use a kernel compiled with "options    TIMER_FREQ=1189200" and 
do "sysctl -w kern.timecounter.hardware=i8254" to get a working system.

Using a kernel with "options    NO_TSC_TIME" does NOT have the effect I 
thought it would have. IF "options    NO_TSC_TIME" is NOT intended to 
disable the use of the TSC, then it would be nice to have another kernel 
compilation option to do so.

I'm not quite sure if any of this would be considered a bug, but as 
Soekris (NET4501) users /may/ also be affected, it thought it prudent to 
drop a note here.

with kind regards,
