Attn rawhide users: 4.2.0-0.rc0.git1.1.fc23.x86_64 causes problems

[Richard W.M. Jones]

With host kernel 4.2.0-0.rc0.git1.1.fc23.x86_64:

- KVM is broken (RHBZ#1236753)

- gnome-shell segfaults all the time (RHBZ#1237060)

Reverting back to 4.1.0-1.fc23 fixes both problems.

Please try 4.2.0-0.rc0.git2.1.fc23 that was built yesterday.  It boots
in KVM for me at least.

I will check in a moment if it cures the above problems, but that
kernel fails in a couple of different ways in device mapper code:

No, that kernel is worse.  In addition to the bugs above, and the LVM
bugs in the other email, there's another bug when running KVM:

No wait, the gnome-shell bug (RHBZ#1237060) looks like it is fixed.
