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 Rgds, > > Regards, > -- > Yves-Alexis
