More info... obsd mounted the nfs folder on /mnt/nas, there is an unknown problem on the io with the nas, and "ls /mnt/nas" locks the console instead of terminating with information on the problem.
Before mounting /mnt/nas, obsd had a hot-swap disk mounted on /mnt/backup, alive and well. After mounting /mnt/nas, "ls /mnt/backup" locks the console as well. ---The evolution of ICT: hardware, software, crapware, abandonware.
