I'm testing the 3.0-0.rc3.git5.1.fc16.x86_64 kernel (on F15)

 I installed device-mapper*, perf, procps and mdadm from rawhide.

  On install it did complain (W) about possible missing firmware for
nouveau and 2 other items (sorry my F15 X session crashed and I lost the
log) - not sure what firmware I should be loading -
xorg-x11-drv-nouveau? What else ?

 Testing on sandy bridge laptop.

 I see a couple of issues that may be of interest (sorry for text wrap)

 regards
