[Bug 1543152] Re: nfs hangs after wakeup from hibernation, kernel 4.2.0-*

 

The system is now in a half-locked state where anything that needs access to the server machine hangs. 
I have temporarily removed the inclusion of a directory on the server from PATH (in .bashrc) which lets me start new terminal windows with bash, not only busybox. 

However. when I tried explicit mounting from the nfs server the terminal
hangs indefinitely which makes me believe that it is the mount command
that should own the problem.

I attach some info from the failed attempts to run apport-collect.

After this I will restart the system and rerun apport-collect

Title:
  nfs hangs after wakeup from hibernation, kernel 4.2.0-*

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  For a couple of tears I have usually not shut down my pc after using it, I just leave it and let it hibernate. 
  (Of course I have also shut down the system completely every now and then.)
  This has worked well but recently with new kernels 4.2.0-* I get problems that I suppose comes from nfs. 
  I have my firefox account and a folder in my PATH on a server with the file system automounted using nfs. 
   - each new terminal window hangs without a prompt
   - a busybox terminal with a simpler PATH works ok
   - when I click on anything in the firefox window it hangs and is greyed-out. The system says "not responding" if I try to kill it

  I have output from 'ps ax', ps -eF' and 'mount' commands that I will attach. 
  What more info do you need?

  Regards,
  Seved
