Having the same issue updated to 6.12.6 from 6.11.5 and hangs at
Triggering udev events: /sbin/udevadm trigger --action=change
for about 20 minutes before i turned it off and rolled it to the backup i made right before the update. Unraid starts no problem. Tried to redo the update and same result, it gets stuck at Triggering udev events I tried booting the usb in different ports but it never wnt anywhere.
Any suggestions?
