I think my hangs (system not restarting from freeze, especialy when 
first starting in the morning) are probably related to the situation 
described in Ubuntu bug https://bugs.launchpad.net/ubuntu/+bug/794112 
and nothing to do with Jeff Layton's freezer patches.

I've seen the error message described in the Ubuntu bug: "Error: state 
manager encountered RPCSEC_GSS session expired against NFSv4 server".  
The bug report hints "Error: state manager encountered RPCSEC_GSS 
session expired against NFSv4 server" and I'm running a 3.1 kernel with 
a Debian squeeze userspace.

I'll update the nfs utils and see whether that improves things.
