Something about timers

Something about timers

[jarmo]

Hi

Just noticed, that if you compile kernel without looking,
Prosessor type and features -> Timer frequency, default is
250ms, you get quite suprising behaviour with your ax25 stuff,
especially 6pack :)
I'd say quite quick actions and in server case crashes :(. That
mean you have both fbb and cluster running in same computer
with 5 user ports.

So when taking forinstance kernel 2.6.13 in use, select timer as 1000ms,
then your normal ax25 timers should work.

Time in AX.25, NET/ROM and ROSE is still being meassured in units of
timer ticks which has not only changed going from 2.4 to 2.6; it's
also differing between architectures.  I've recently sent out a set of
three patches to standardize that on ms.  That's probably a too small unit
so I think I'm going to change that again before submitting to upstream.

Any crashes you may see are certainly unrelated to this.
