I did get the 5.15 kernel recompiled after recompiling GCC with new headers and other related stuff, including Glibc. The system should be pretty solid on 5.15 now. I'll eventually do another full pass. Sometimes you have to go back and forth with the toolchain. I messed up a wee bit on grub, but no sweat, SystemRescueCD to the rescue: ``` qemu-system-x86_64 -cpu qemu64 -enable-kvm -smp 6 -m 12G -boot d -cdrom systemrescue-12.02-amd64.iso -drive file=/dev/sdb,format=raw ```
