Hi,
some of my ppc qemu tests crash with the following log message.
VFS: Cannot open root device "hda" or unknown-block(0,0): error -6

A complete boot log is available at

Bisect points to commit 'drivers/of: Fix depth when unflattening devicetree'.
Reverting this commit fixes the problem. Bisect log is attached.
I've pushed out a fix this morning with an updated version of that
patch [1]. Please test.
The problem is no longer seen in next-20160520.
Thanks,
Guenter
