Boot freezing after kernel load - root on zfs
Ben Woods
After shutting down to connect a new IP KVM switch (VGA and USB), my
FreeNAS mini hardware is no longer booting FreeBSD with root in zfs (no
encryption) - it is getting stuck after the kernel finishes loading and it
tries to mount root and start_init. It just stops printing any more output
to the screen, but I know the keyboard is working as ctrl+alt+delete works.
I suspect this could be due to hard drives names being re-ordered (e.g.
what was ada0 is now ada1). I have 2 SATA3 SSDs in a zfs mirror for root
(showing as ada4 and ada5 during boot), and 4 SATA3 HDDs in a raidz2 with
geli for further storage (showing as ada0-3, but these are only mounted
during rc init - after the point the boot process is getting stuck). I have
no USB storage, although the IP KVM may present a virtual disk for loading
media remotely.
I am running 12-CURRENT, but know the recent upgrade is not the issue
because I can’t load from the previous boot environment either.
Is anyone able to recommend a fix or a way to troubleshoot further? Please
see below a link with screenshots at the end of the boot where it gets
stuck.

Thanks in advance for any help!
