I was able to diagnose problem and it is not related to CAM as I've 
thought initially. It is related to GEOM spoiling mechanism.

During boot process fsck opens checked disks for writing, while root at 
that time mounted as read-only. Disks close by fsck causes spoiling of 
the root partition's GEOM VFS, that with r238886 change made it 
inaccessible.

I've reverted that GEOM VFS change at r238892, that should fix the 
problem until better solution will be found.

I'm sorry.
