(FireWire audio came last, in 2.6.32.) There is now good and extensive experience with the newer stack from deployment in Fedora since F7 as well as by enthusiast users of other distributions. The new drivers have consequently been recommended as the default ones since 2.6.33, in order to fix some severe usability problems of FireWire on Linux due to limitations of the old stack. It is now high time to announce when the obsolete drivers will be removed. Signed-off-by: Stefan Richter --- Removal in 2.6.36 should be OK too, but one of the Linux FireWire audio driver (ffado) developers recommended 2.6.37 since the current generation of pro-audio oriented distributions still ships the old drivers as default.
