 I applied the patch, compiled the kernel and rebooted. NFS read access
 seems to work as before. When I try to write to the server, the server
 locks up solid, i.e. I do not even get a kernel panic reported on the
 serial console, so I can't give you a backtrace or anything. I had to
 disconnect the cable from the wall outlet to the power supply to restart
 it. It came up without problems, though.
