[linux-audio-dev] DRI + Jack conflict?

[Dave Robillard]

Through a painful process I'd rather not go into, I discovered that Jack
will not run in realtime mode with my Radeon's 3d drivers loaded.. I get
the error "cannot lock down memory for RT thread"

My idea-for-the-day was visualisation of realtime jack audio (from live
performance); needless to say my day ended up far less interesting than
I had hoped. :)

Is this a known problem, or screwy system configuration on my part?

(XFree-4.3.0, Radeon9000 Pro, Linux 2.4.24 lowlat)
