NetBSD omniacet.local 6.1 NetBSD 6.1 (GENERIC) i386
>Description:
I was following NetBSD NFS guide for connecting to kubuntu(trusty) nfs server. When mounting a directory, kernel crashes with dumps saved in /var/crash.
>How-To-Repeat:
Server configuration:
/etc/export:
/export 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)
/export/users 192.168.1.0/24(rw,fsid=0,nohide,insecure,no_subtree_check,async)
/export/users directory is a mounted (-o bind) /tmp/export directory.
Client configuration:
/etc/rc.conf:
rpcbind=yes
nfs_client=yes
lockd=yes
statd=yes
Then I use
mount -t nfs 192.168.1.4:/export /mnt
Fs is mounted correctly, but when I cd into it, kernel reboots and crash files are generated.
>Fix:
I changed server configuration (/etc/export) to
/tmp 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)

Please let us know (1) the panic message, and if possible (2) the
backtrace saved in the crash dump.
Without further information there is really nothing we can do.
Also:
> /export 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)
> /tmp 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)
Do you mean that you changed which directory is exported and it no
longer dies? Because nothing else in there seems to be different.
