NFS on ARM/IXP435

Well, ktrace didn't help me much... Here is the output of kdump :

Bus error (core dumped)

And top shows that mount_nfs is stuck on RPC stuff :

  764 root          1   4    0  3436K  1148K rpccon   0:03  0.00% mount_nfs

I've tried compiling strace from ports, but it appeared to be supported 
on i386 only.
