We used to have a 100% CPU issue with knotify a while back in Mdv, but I
thought we'd fixed it. It relates to how Phonon works with streams. All
the backends are broken in one way or the other :(. IIRC tho' knotify
does some strange things with it's sound output... It never bothered me
quite enough to get my hands dirty and look at the code however. I've
seen it hogging the alsa hw:0 device in the past tho'. Nasty.
The problem with waiting until reboot is that the ACLs for the device
nodes may not be written correctly at boot time for whatever reason, and
it's this boot that causes the problems. Running PA manually after
checking the ACLs is a good way to verify everything is setup correctly.

If you're a KDE man (which is sounds like you are) then MAndriva and
OpenSuse generally get the best write ups for KDE related stuff.

Works fine here, perhaps it's specific dkms packages?

Hmm, I have ccache running fine here too.

Are you building an RPM via mandriva's packages because if so, you are
aware that it's building several separate kernels for various different
purposes. You can edit the SPEC to not generate all the sundray kernels
and only build the one you are interested in.

Hmm, strange. I don't really subscribe to the expert list much... cooker
tends to be what interests me more.
You should hang out in IRC. People tend to be pretty helpful generally.
