I know it... :'( But as you rebuild the kernel image the updated compiler
may come a bit later w/o needing another kernel update ?

Anyway if you want someone to test the updates please push the updated
packages to stretch-p-u and I'll tell you if it works on my four boxes
which are :
- An Intel Core i7 4790 w/ NVidia blob 384.111
- An AMD Phenom 9850 w/ NVidia blob 384.111
- An Intel Core i7 4800MQ laptop
- An Intel NUC Atom Apollo Lake
