[I've cc'd some folks that recently committed onto main's stand/ or did the llvm14 toolchain merge. I've no clue what makes the difference.] Note: the MACCHIATObin Double Shot has a EDK2 based UEFI/ACPI context for how it is set up to boot. In trying to update a MACCHIATObin Double Shot to a main vintage with llvm14 I got boot attempts that look like the below at the tail of its visible activity (serial console): QUOTE Loading kernel... /boot/kernel/kernel text=3D0x2a8 text=3D0x91b040 text=3D0x216434 = data=3D0x1b8128 data=3D0x 0+0x2ae000 0x8+0x130980+0x8+0x157b86 Loading configured modules... /boot/kernel/cryptodev.ko text=3D0x16c3 text=3D0x27a0 data=3D0x628+0x10 = 0x8+0xcd8+0x8+ 0x96c /boot/kernel/zfs.ko text=3D0xa81a0 text=3D0x209310 data=3D0x26a88+0xba46c = 0x8+0x32a78+ 0x8+0x2c37e /etc/hostid size=3D0x25 /boot/entropy size=3D0x1000 No valid device tree blob found!
