I've been running cpufreqd for the last few days with full logging
enabled. the system powered off just now - I don't see anything
anomalous in /var/log/syslog (and no mention of frequency changes).
I've attached the relevant section of the log, showing everything in
syslog for the last few seconds of uptime. The last line is the system
booting (with the clock reset).
I've now disabled cpufreqd and am testing powernowd to see if I get the
same behaviour.
Subjectively, it seems like these resets happen during times of higher
system load: Fan running, disk or memory access occurring, cpu somewhat
busy.
