Recently, I had a problem with the graphics/drm-kmod hanging on boot in multi-user. My fix was to switch to graphics/drm-legacy-kmod, which at least lets the system boot again. I figure the newer graphics/drm-kmod no longer supports my old radeon card. > now also this second disk no longer boots,it stops in Loading kernel > modules.Further how can I mount ada0p3 partition rw on this second disc > considering that bot are zfs?(I could not figure this out mysel)I plan to > reinstall on the second disksincerelyFilippo The easiest way to be able to edit the configuration of the existing system to fix things is to boot it in single user mode (press "2" from the loader menu). When you get to the single user prompt, you can then mount your ZFS file systems for writing as follows: mount -uw / /etc/rc.d/zfsbe start /etc/rc.d/zfs start You can then, e.g., edit /etc/rc.conf and remove the problematic kld_list entry.
