[top output snipped]
FWIW, I get the same symptoms (3.2-STABLE dual CPU). 'ps' and 'vmstat' both
behave the same way (they report 0 % CPU usage for all processes even under
heavy load).
Note, I tried it after rebooting nearly 3 weeks ago, and it was not
working. Then I tried it when I received your email just to double
check. It was working! So I ran 'xosview' (are you running that,
too?), and it was working fine for about 10 minutes. Then I got the
following error message and all indicators (top, ps, vmstat) resumed
their bogus '0% CPU usage' behavior.
Warning: CPUMeter meter had a zero total field! Would have caused a div-by-zero exception.
Warning: the CPU tick counters are not changing. This could
be due to running a kernel besides /netbsd (or the equivalent for FreeBSD).
If this is the case, re-run xosview with the -N kernel-name option.
If not, then this is a bug. Please send a message to
bgrayson@ece.utexas.edu, in addition to any send-pr bug reports
(or in lieu of -- it ought to get fixed faster if you contact me
directly). Thanks!
For those that don't know, xosview is a GUI CPU/etc. meter (see
/usr/ports/sysutils/xosview).
