The Pine64+ 2GB is doing a buildworld buildkernel that will not complete for some time.] From a reboot after having deleted /boot/kernel/linker.hints : Mounting local filesystems:. ELF ldconfig path: /lib /usr/lib /usr/lib/compat /usr/local/lib /usr/local/lib/perl5/5.26/mach/CORE Building /boot/kernel/linker.hints then later rebooting again: VT: init without driver. KLD file umodem.ko is missing dependencies kldref for cross-builds could still be a problem but it need not be the only one. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)help
