contigmalloc1 panic on install

[mark tinguely]

What kind of video is in that laptop? Sounds like the kernel is that
you are booting in the 4.8 case is the GENERIC. If you can get the
rescue disk to boot to single user mode, you should compile and install
a kernel that has the kernel debugger compiled in.

just a quick look there are several places that a 0 sized contigmalloc()
could accidently occur.
