On this machine, the previous KASLR kernel from 26th of January was OK. I did again a clean build and repeated on a second build host to make sure it is not a local snafu.

The machine is a VirtualBox guest and has been running GENERIC_KASLR since that was made available; now obviously on today's GENERIC or on the last good GENERIC_KASLR.    
>How-To-Repeat:
On a new HEAD installation, follow the instruction to switch to KASLR. 

Also confirmed on a new installation.  
>Fix:
N/A
