The system just completed an OS build/install cycle on r331088, the only obvious change is some additional console output, which ends with >> FreeBSD EFI boot block Loader path: /boot/loader.efi Initializing modules: ZFS UFS Probing 5 block devices......** done ZFS found no pools UFS found 2 partitions Consoles: EFI console Command line arguments: loader.efi Image base: 0x379ad008 EFI version: 2.05 EFI Firmware: Das U-boot (rev 0.00) FreeBSD/arm64 EFI loader, Revision 1.1 (Sun Mar 18 04:46:21 PDT 2018 bob@www.zefox.org) BootCurrent: 0000 BootOrder: 0004 0000[*] 0000[*] 0000[*] 5990 3af8 0000[*] 0000[*] ed78 3ab2 0000[*] 0000[*] 28ec 3af6 0000[*] 0000[*] 0067 0000[*] 0000[*] 0000[*] 02e0 3ab4 0000[*] 0000[*] 5000 3af8 0000[*] 0000[*] ee20 3ab2 0000[*] 0000[*] 2a48 3af6 0000[*] 0000[*] 5990 3af8 0000[*] 0000[*] 6000 3794 0000[*] 0000[*] 6000 3394 0000[*] 0000[*] 4000 0000[*] 0000[*] 0000[*] d520 3ab3 0000[*] 0000[*] 5000 3af8 0000[*] 0000[*] 4000 0000[*] 0000[*] 0000[*] 1000 0000[*] 0000[*] 0000[*] 6000 3394 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 02e0 3ab4 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] 0000[*] ff20 3ab3 0000[*] 0000[*] Loading /boot/defaults/loader.conf /boot/kernel/kernel text=0x4e1587 data=0xe7320+0x70243c syms=[0x8+0x9e2b0+0x8+0x7e497] /boot/entropy size=0x1000 Hit [Enter] to boot immediately, or any other key for command prompt. Booting [/boot/kernel/kernel]... Using DTB provided by EFI at 0x8004000. At this point the machine becomes stuck. Power-cycling allows an older kernel, built on r326343, to come up normally. Both the functional and non-functional kernels were built using a custom config file, which can be seen at http://www.zefox.net/~fbsd/rpi3/kernel_config/ZEFOX Thanks for reading, I'd be grateful for any workarounds. bob prohaska
