Hi, while testing on my workstation I had some optimizations flags in place while I did buildword of 10-STABLE. The system failed to boot because of a not working loader.efi I replaced the loader.efi with the one from the STABLE snapshot media and the sytem loaded up correctly and worked as I could see. To verify I removed all custom flags from my make.conf and rebuilt world again which leads to a fully working system again. Not sure if its a real bug or needs some more investigation. Here are the flags I had in place: CPUTYPE?= core-avx2 MAKE_JOBS_NUMBER?=8 OPTIMIZED_CFLAGS=YES BUILD_OPTIMIZED=YES WITH_CPUFLAGS=YES WITH_OPTIMIZED_CFLAGS=YES Regards, Dominik

Optimization flags lead to not working loader.efi
