I haven't been able to /safely/ use it from 4.8 on. I remember some talk on the list sometime ago and then it seemed to be resolved, as the discussion ended. So I thought it was fixed. Seems not. :( My scenario; mount host off root: mount script exec'd follows... #!/bin/sh - mount -t nfs host.domain.tld:/ /host mount -t nfs host.domain.tld:/var /host/var confirm mount... # ls /host .snap COPYRIGHT bin ... usr var tmp OK looks good... # cp /path/to/approx/10Mb/file /host/path/to/dest/dir/ Fatal double fault eis 0x0blah eiblah blah0x panic double fault no dump device defined rebooting in 15sec... Hmmm... that's not good. :( ------8<---SNIP---8<-----SNIP-----8<------- My final solution was to change the lines in /etc/rc.conf from: nfs_client_enable="YES" nfs_reserved_port_only="YES" nfs_server_enable="YES" rpc_lockd_enable="YES" rpc_statd_enable="YES" rpcbind_enable="YES" to: nfs_client_enable="YES" nfs_reserved_port_only="YES" nfs_server_enable="YES" #rpc_lockd_enable="YES" #rpc_statd_enable="YES" rpcbind_enable="YES" Making those changes ended the "Fatal double fault && reboot in 15 seconds..." My nic is: ifconfig_nve0 Thanks for reporting the /buggy/ nve driver. So there are no issues with the nfe driver? Thanks again. --Chris -- panic: kernel trap (ignored)
