Earlier this year there was some discussion about kernel version numbers after 4.9.255 and 4.4.255. Problem was 8-bit limitation for SUBLEVEL number in stable kernel versions. The fix was to freeze LINUX_VERSION_CODE number at x.x.255 and to continue incrementing SUBLEVEL number. Seems there are more more fallout from that decision. At least some versions of glibc do not play well with larger SUBLEVEL numbers.

Above upgrade works normally if I edit top level Linux source Makefile to say "SUBLEVEL = 0" and re-compile new kernel.
I am not pointing any fingers here, but it seems that either glibc code or stable kernel versioning is messed up.
