We use IP for access. We mount it with the mount_nwfs command.

My working server (FBSD 4.11) and the non working server (FBSD 6.1) are both connected to the some switch.

I also got an kernel trap = 12 after i mounted the novell volume.

Are you using IPX or IP for access to the Netware server? What version
of Netware are you using? We mount our Netware shares on-demand, but
only because that suits our access pattern...

We have seen issues with the Netware connection "going away" depending
on how you configure the IPX network numbers on FreeBSD and how you're
running IPXrouted. We've also seen issues with connectivity to Netware
servers with both IP and IPX that are due to network topology
problems... moving the FreeBSD server to a different location on the
network resolved our connectivity issues at one site.

What command are you using to create the initial Netware connection? A
mount_nwfs command or ncplogin ?
