Hello,
I've met some quite strange reboots recently on my home gateway. I'm
trying to reduce its power consumption, so I've loaded the cpufreq(4) drive=
r,
and enabled powerd. After this the box started to reboot randomly all over =
the
place. I started to think what can cause the trouble, removing the cpufreq(=
4)
support would be too trivial, so I've removed the ALTQ references from my
pf.conf, and surprisingly these accidental reboots gone away.
My guess is ALTQ has some problems with cpufreq(4). Before submitting a PR =
on
this, could someone also check this configuration, to be sure on this?
