[7-STABLE] ndis interacts badly with powerd

[Patrick Lamaizière]

Hi,

[7-STABLE/i386-SMP]

When I enable powerd, ndis takes all the CPU. Powerd alone and ndis
alone works fine.

The kernel threads "Windows DCP0" and "ndis0 taskq" run at
100%. But the machine is still running (but is very very slow), I can
kldunload my ndis module and all is ok.

I tried with a kernel (GENERIC) without SMP but there is the same
problem.

Any idea? Thanks.
