[Kernel-packages] [Bug 1566726] Re: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]

[Tim Wescott]

Kamal Mostafa:

You were correct.  Installing the "extras" made my track ball work.  The
computer has now held up for several hours, which is considerably longer
than it survived under the -69 version.  So -- I think the -70 fixes it,
at least for me.

[Kernel-packages] [Bug 1566726] Re: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]

[Kamal Mostafa]

Tim Wescott - Another possibility for your trackball problem... It might
just be that your trackball driver is actually in the "linux-image-
extras" package, so manually installing the -70 "linux-image" .deb using
the link I provided in comment #9 is insufficient.  Try installing both
of these:

https://launchpad.net/ubuntu/+archive/primary/+files/linux-
image-3.16.0-70-generic_3.16.0-70.90~14.04.1_amd64.deb

[Kernel-packages] [Bug 1566726] Re: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]

[Kamal Mostafa]

Tim Wescott - Its seems most likely that your trackball problem is a
separate issue introduced between -67 and -69.  Please verify that by
checking your trackball with -69 installed.  Assuming that the trackball
problem happens there too, file a new bug report.  (If on the other
hand, you find that -70 really does introduce the trackball problem,
certainly let us know here!).  The "-69" kernel (3.16.0-69.89~14.04.1)
is the current main -updates kernel version for linux-lts-utopic, so it
should be available to install via your standard apt sources.

[Kernel-packages] [Bug 1566726] Re: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]

[Tim Wescott]

just loaded the above 3.16.0-70 kernel -- I didn't stay long enough to
see if it solves the problem, because it killed my trackball (and old
USB Logitech).  3.16.0-67 works, though (it's what I'm using at the
moment).

[Kernel-packages] [Bug 1566726] Re: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]

[Kamal Mostafa]

Thanks for the confirmation Philip.  The official fixed kernel is now
ready in -proposed; We'd like confirmation (from any affected user) for
this kernel as well.

Quick link to the -proposed amd64 .deb (easier than the full
"EnableProposed" method):

[Kernel-packages] [Bug 1566726] Re: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]

[Kamal Mostafa]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Just to pile on, ran into the same issue in my CS computer lab. causing
multiple systems to lock up. Thank you for the quick fix.

[Kernel-packages] [Bug 1566726] Re: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]

[Kamal Mostafa]

To address this bug, we're going to release 3.16.0-70.90~14.04.1
comprised of just this fix.  That kernel will become available in the
-proposed archive in the next day or two (an announcement will be posted
here).

In the meantime, a preview build of that kernel is available here (this
replaces jsalisbury's test kernel from comment #4):

http://kernel.ubuntu.com/~kamal/lp1566726.0/

Affected users, please confirm that preview kernel resolves the problem
(likely only the linux-image-3.16.0-70...deb needs to be installed).

[Kernel-packages] [Bug 1566726] Re: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref]

[Joseph Salisbury]

It looks like the offending commit is already reverted in lts-utopic -next:
  
a907233 Revert "drm/radeon: hold reference to fences in radeon_sa_bo_new"
72a5cff drm/radeon: hold reference to fences in radeon_sa_bo_new


I built a test kernel of -next, which will be the next release.  The test 
kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1566727/

Can you test this kernel and see if it resolves this bug?

Title:
  System freeze after update to 3.16.0-69-generic [NULL pointer
  reference in radeon_fence_ref]

Status in linux-lts-utopic package in Ubuntu:
  New

Bug description:
  So far I've seen this happen on 2 systems today. On one only X froze, the 
other one panicked.
  Booting into 3.16.0-67 is the workaround for now

  ProblemType: KernelOops
  Annotation: Your system might become unstable now and might need to be 
restarted.
