[Kernel-packages] [Bug 1696240] Re: linux 4.10 and AMD Polaris11 card -> graphics crash

2017-06-08 Thread Kai-Heng Feng
Probably a good idea to use out-of-tree amdgpu.ko for now, until Artful
release.

Download the driver from [1].
Extract the driver.
There's a package that is named "dkms", install that package:
$ sudo dpkg -i *dkms*.deb

If there are missing dependencies:
$ sudo apt -f install

Title:
  linux 4.10 and AMD Polaris11 card -> graphics crash

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Zesty:
  Confirmed

Bug description:
  Using 4.10.0-22-generic from Ubuntu and running any of the Unigine benchmarks 
(Heaven-4.0, Valley-1.0, Superposition-1.0) causes the screen to go black and 
the graphics system to crash.
  The graphics card's fan stops working and sensors reports 511C, clearly wrong.

  I can still login via SSH and attempt to stop X, however the
  application (e.g. heaven) just remains in a zombie state and the
  system is unusable, I can't start X again. In fact the graphics card
  ends up in a pretty bad state, because if I press the reset button the
  UEFI BIOS is not able to detect it anymore, I have to power the whole
  system off and on again to make the card work.

  Upgrading to mainline 4.11.3 avoids this problem: all 3 benchmarks are
  running fine, with no crashes.

  I've attached two dmesgs: one with the default, where IOMMU is on and I get 
lots of AMD-Vi warnings logged:

2017-06-07 Thread Joseph Salisbury
Would it be possible for you to test the latest upstream stable kernel?
Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the
latest v4.10 stable kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, 
please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as 
"Confirmed".

Thanks in advance.
