[Bug 1332964] Re: Xorg crash after resume: nouveau failed to idle channel

  Thread Previous • Date Previous • • Thread Next 
Andris Berzins, 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 as it will automatically gather
and attach updated debug information to this report:

apport-collect -p xorg 1332964

Please ensure you have xdiagnose installed, and that you click the Yes
button for attaching additional debugging information.

As well, given the information from the prior release is already
available, testing a release prior to the development one would not be
helpful.

Thank you for your understanding.
