["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Brian Brunswick, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  NFS lockup (readonly udp nfsv4 gigabit)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I've got a 12.04 precise client with lots of mounts like this.

  morgul:/n2 on /n2 type nfs (ro,udp,nolock,vers=4,addr=192.168.10.212,clientaddr=192.168.10.216)
  morgul:/n1 on /n1 type nfs (ro,udp,nolock,vers=4,addr=192.168.10.212,clientaddr=192.168.10.216)

  Periodically, they all lock up, stuck until reboot. Some processes
  (df) stuck like that respond to ctrl-C, others don't (ls)

  Networking is fine, and interestingly I can remount the export from
  the server on another path on the same client and the new mount works
  fine, while all the old ones are still stuck. No useful messages in
  syslog.

  The server is runnig oneiric, 64 bit.

  This seems like a recurrence of NFS bugs that people have reported
  before, which have been claimed to be fixed. Its clearly not. I get it
  randomly after transferring a few GB of data. (mythtv playback)
