It is looking more likely to me that enabling lock profiling does mask
the freeze. I ran for more than 10 hours yesterday with lock profiling
enabled and did not observe a single freeze. After about 7 hours, I
stopped the lock profiling and within 20 mins or so, I experienced a
NINE MINUTE freeze!! On re-enabling the lock profiling, I ran for about
3 more hours with no further freezes.
At the time of that long freeze, all I was doing was typing an email
message. The load average was almost 0. Mail client is claws-email.
Also running but idle were firefox, ical, several xterms, fvwm & its
children (Fvwm{Buttons,Event,Pager,IconMan}), xload and xclock. And
xorg which uses the xf86-video-intel driver. Daemons running were
wpa_supplicant, dhclient, devd, syslogd, cupsd, ntpd, powerd, sshd,
sendmail, cron, moused and xdm. That is all.
I had only one browser window open, the last page I'd viewed there
was one containing some flash, I have linux-flash7 installed and
nspluginwrapper to make that work in the native browser.
All code (kernel, world and ports) have been compiled locally - there
are no packages installed. Kernel is RELENG_7 from two days ago,
world and ports are about one month old.
If I get time today I may have a go at getting schedgraph info
instead of continuing with lock profiling.
