I don't know. I tested -8 only on new kernels.

amd64.
Standard vanilla kernels from git. No special flags.

Reproducible: I tried a some kernels with old and new compiler (yes: I 
started to git bisect the kernel). With old compiler I have bootable 
kernel, with new compiler the kernel block at very beginning.

So if you have a hint about what patch should I remove/apply, I could 
check if it solve the problem.
