[PlanetCCRMA] fc6/fc7: YAK!! and jackmixer

[Fernando Lopez-Lezcano]

YAK!! (Yet Another Kernel...). Oh well, a new realtime preemption kernel
for fc6 and fc7. Based on 2.6.21.5-rt17 (package version is
2.6.21-0182.rt17.1), it fixes a problem with some BUG traces I was
getting on our hardware with the skge ethernet adaptor, most probably
solves equivalent problems on other drivers as well. As usual, thanks to
Ingo for his work!

Updated JackMix to version 0.3.1 on fc6 and fc7. 

Enjoy!
