cpufreq_conservative should be marked broken on SMP - I have used it on UP
boxes without trouble but I can't even safely modprobe it on SMP - it nearly
ate my filesystem.
And there seem to be multiple different problems with it - I get different
oopses depending upon whether or not I have loaded it before or after the
ondemand module. Weird enough - cpufreq_conservative shares much of it's
code with cpufreq_ondemand, which works without any problem.
Let me know if anyone has objection to marking cpufreq_conservative
depends !SMP - I am planning to submit a patch soon.
Parag
