Bug 101483

Tested  upstream kernels 4.12-RC1 - RC5

I have set the importance to "high, critical". See comment #26 https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1639517

Have you tried iommu=soft kernel parameter?

you should provide the log of a faulty boot (i.e. dmesg), showing the different boot modes. That would help the devs to see what actually happens

1. Testing amdgpu-pro-17.30-458935 - installed kernel  4.8.

Installing amdgpu-pro-17.30-458935 according link -and adding user to group video 
After installing: logout.
Then - a Login wasn't possible:
login started - and was finished a short time later with login-screen.
Reboot without workaround parameters:
boot process started:
gray screen - flash - black screen - messages - splash screen - messages - read in line:  maintenance or continue -> continue - error messages - stopped by SysReq B - reboot without workaround parameter  - similar cycle.  stopped by SysReq B.
Now reboot was not possible.
No item in EFI/esp. I tried to fix it using a live System and my "primary" installation Kubuntu - it didn't work. So I reinstalled my "primary" System Kubuntu.
Now  starting the test installation (workaround parameter nomodeset) failed - file system repair of system and data partition.
I didn't repeat the test. I have no log files.

=======================

2. Testing amdgpu-pro-17.30-465504 - installed kernel  4.10.

I tested several times dkms in September and October 

A: Installing procedure
Playing back a saved system partition,

installing dkms according link- group video -> <actual user>.

A few times I installed the AMD proprietary microcode driver. 

After installing reboot (workaround parameter)
Login wasn't possible - a started login was finished with login screen.

B.Test

Boot without workaround parameter.
optional kernel parameter "noplymouth boot_delay=<up to 400>
As boot process was never finished, reboot using SysRq (-> C:)
Starting my "primary" installation Kubuntu and run fsck of the dkms system partition,

C. results
The boot process was never finished;
reboot either SysRq + b or SysRq + r|e|i|s|u|b.
Results  were sometimes reproduced - but it was not predictable when they were.
Normally there was a never ending stream of messages incl. some error messages or a loop of always the same messages - all these tests were stopped by SysRQ.
Some test runs ended with kernel panic - then a restart was only possible by "hard off" (several seconds "power off" button).

The results of fsck also were not reproducible. Using SysRq + b : fsck shows error messages.
Using SysRq + r|e|i|s|u|b: sometimes filesystem state was clean. Only in that case boot runs of that installation were comparable. 

During some test runs (kernel parameter "boot_delay") I took series of photos - but none of these series is complete (partly the messages on these photos are not readable). I don't attach any.




A method how to redirect boot messages printed to the system console to a file I didn't find, respectively I didn't manage to run bootlogd - available in the repositories of Ubuntu; I couldn't find detailed tips, how to configurate  bootlogd

to the dev team:
Since 18 month I'm using Ubuntu on my notebook with restricted functionality - esp graphic functions; without kernel parameter "nomodesetting" when booting, the screen  remains black. I posted this situation in Nov 2016 - but up to now there is no solution available  (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1639517, bug #1639517; https://bugs.freedesktop.org/show_bug.cgi?id=101483).

I ask you, whether in the foreseeable future there will be an driver available for "my" processor A10-8780P APU, R8 extreme edition 4C+8G,display     Carrizo and display     Topaz XT [Radeon R7 M260/M265].
Who can give me an answer?

This is an upstream bug tracker, not an Ubuntu one. If the problem is fixed with upstream 4.15-rc3, please resolve this report as fixed.

Today I set this bug to "resolved fixed", importance to "medium, normal". Afterward I checked some hw infos,
 e.g. in the result of "sudo lshw -short" I miss the following line: 
/0/100/3.1/0                 display     Topaz XT [Radeon R7 M260/M265]
So I assume, at the moment graphic and the A10-8780P APU is not yet full supported.
