My system starts booting, loads kernel and all kernel modules ( I tried to remove all of them except of zfs from loader.conf, but it didn't help) and = then at the moment of mounting root zfs pool it momentarily shows some lines of error messages and PC immediately reboots. As far as my root zfs pool takes= the whole disk space I have no space for non-zfs kernel dumps and therefor ther= e's no any dumps saved. Nothing's written in logs too, because (as I understand= ) it happens before system can open any file to write. The reboot starts too fast and I cannot even make a photo of the screen to recognize what errors exact= ly happen. I tried to update the system to the most recent version from Mar 08 2018, but the problem still exists. Is there any way to make the system not reboot immediately after root zfs p= ool mounting error, but freeze and just show me the error until I press a key or something like that? Otherwise I'm not able to pick any additional informat= ion. --=20 You are receiving this mail because: You are the assignee for the bug.=
