 I see the similar problem on i386 NFS server running ipnat
 and sparc client using UDP 8k block without ipnat, but
 I have not confirmed well if ipnat actually causes the problem.
 
 "options NFS_BOOT_RWSIZE=1024" on the client kernel or using
 NFS via TCP seems to work, so ipnat might have some bugs around
 fragmented UDP packets?
