dmesg output for kernel-4.16.16-200.fc27.x86_64

Created upstream bug at https://bugzilla.kernel.org/show_bug.cgi?id=201295

From upstream:

"Suspicious section from kernel 4.18.16 dmesg output:

[    2.801753] amdgpu 0000:09:00.0: Direct firmware load for amdgpu/polaris11_mc.bin failed with error -2
[    2.801754] mc: Failed to load firmware "amdgpu/polaris11_mc.bin"
[    2.801852] [drm:gmc_v8_0_sw_init [amdgpu]] *ERROR* Failed to load mc firmware!

[    2.802218] amdgpu: probe of 0000:09:00.0 failed with error -2

Error -2 is -ENOENT, "No such file or directory", so the amdgpu/polaris11_mc.bin file is missing where the amdgpu module is loaded from (could be the initrd).

This is a configuration error, not a bug."

Can you check that the kernel config includes all necessary bits in the initrd image?

Workaround:
Boot into latest kernel, and run:

  dracut --force -v -I "/usr/lib/firmware/amdgpu/*"

Thanks

Workaround works

dracut configuration workaround

The attached '99-amdgpu.conf' file goes in /etc/dracut.conf.d/, and is meant to be a more permanent workaround. It forces every initrd image to always contain the amdgpu and radeon firmware.

This message is a reminder that Fedora 27 is nearing its end of life.
On 2018-Nov-30  Fedora will stop maintaining and issuing updates for
Fedora 27. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora  'version' of '27'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 27 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Since kernel-4.19.10-200.fc28.x86_64 this changed to:

in spite of the attached '99-amdgpu.conf' file.

New firmware should arrive from upstream

Firmware arrived in linux-firmware-20181219-89.git0f22c852.fc28.noarch

Also, dracut.conf.d files have started appearing again with each kernel update (e.g. amdgpu-4.19.13-200.fc28.x86_64.conf).

I will test if things work again without the '99-amdgpu.conf' file workaround...

Works on current kernel without workarounds (kernel-4.19.13-200.fc28.x86_64)
