>Description:
constant 1.00 loadavg, with top saying:
CPU states: 0.0% user, 0.0% nice, 0.0% system, 1.6% interrupt, 98.4%
idle
(With both SMP and non-SMP kernels, with the default scheduler)
After recompiling the kernel with SHED_ULE, loadavg dropped to the constant 0.99, so it still does not exactly look right.
PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND
11 root -16 0 0K 12K RUN 8:48 97.17% 97.17% idle
27 root -44 -163 0K 12K WAIT 0:07 0.00% 0.00% swi1: net
28 root -48 -167 0K 12K WAIT 0:01 0.00% 0.00% swi8: tty:sio clock
[...]
And kern/21155 pr does not exactly include the possible fix (nor hints).
>How-To-Repeat:
to reboot and wait, nothing more.
