Sorry for possibly mentioning this twice.

When I try to boot with the fuse module in /boot/loader.conf I get
something like this:

Fatal trap 12:

...

fault virtual address = 0xcd
instruction pointer = 0x20:0xffffffff80eec062
stack pointer = 0x20:0xffffffff8420e580
frame pointer = 0x20:0xffffffff8420e670

...

Then there is a prompt:
db>

or something, but it doesn't respond to keyboard input and I have to reboot.

Somehow I managed to unload all modules from the boot prompt and reboot.
After that, I rebooted without the fuse module in /boot/loader.conf and
things work fine.

I have tried to boot again with fuse in /boot/loader.conf, and the first
boot I get to a mountroot
prompt which I am now reading up on.

Maybe this is the same as Michael Gmelin is working on.

Regards,

Per Gunnarsson
