Hi,

It seems that last bugfix to os/timer.c (1.3.2.2) introduced another bug:

outp(BV(CS00) | BV(CS20) | BV(WGM01), TCCR0);

makes timer0 output compare ISR called 128 times too fast (wrong prescaler
setting).

Should be:

outp(BV(CS00) | BV(CS02) | BV(WGM01), TCCR0);

The bad news is that 3.4.2 release was published with sources containing
os/timer.c (1.3.2.2), which completely freezes applications using NutOS
recompiled with NUT_CPU_FREQ defined.
