While experimenting with pmcstat I found that my problem seems to be mouse-related. I did several tests - booted, logged in with xdm, started an xterm and left 'pmcstat -S instructions' running in xterm to see where it freezes. As long as I don't touch the mouse, pmcstat output keeps scrolling by at high speed. I can wait several minutes and it just keeps scrolling. But when I start moving the mouse, soon (probably 10-20 cm of mouse movement, but I haven't done any real measurements ;) ) there is this "hiccup". As I said earlier, this happens only once during the session. The same test can be done outside X, on the text console, and the behaviour is identical. I tried with two generic 2-buttons-and-a-wheel PS/2 mice and the results are identical. I don't have any USB mice at hand immediately. # grep mouse /etc/rc.conf: moused_enable="YES" # grep psm /var/run/dmesg.boot psm0: irq 12 on atkbdc0 psm0: [GIANT-LOCKED] psm0: model IntelliMouse, device ID 3 At that point it seems that faulty hardware can't be ruled out (dying mouse port on the motherboard?). But it seems a bit strange that the problem appears exactly once during the session. I'll try with USB mouse tomorrow. -- Toomas Aas ... Enter any 11-digit prime number to continue.
