Description R Ghetta 2019-02-28 20:39:31 CET

Description of problem:
when booting with kernel-desktop-4.14.89 or 4.14.100 the boot process stops after giving "fb: switching to amdgpudrmfb from EFI VGA"
Googling around I found https://bugzilla.redhat.com/show_bug.cgi?id=1659810 hinting to a obsolete firmware package.

4.14.78 works perfectly
My video card is a Rx550, identified as                 \
description: VGA compatible controller
product: Baffin [Radeon RX 550 640SP / RX 560/560X]
configuration: driver=amdgpu latency=0

booting with nomodeset works, but then x cannot start

Comment 1 R Ghetta 2019-02-28 21:09:02 CET

btw, the boot process continues even after the "fb: switching ..." message, only the graphics card is affected.
looking at dmesg via ssh I see

"mc: Failed to load firmware "amdgpu/polaris11_k_mc.bin" is the same message noted in the redhat bugzilla linked above.
In their instance they pushed a new firmware package containing https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu/polaris11_k_mc.bin  (see comment 2)

Comment 2 Thomas Backlund 2019-02-28 22:08:17 CET

Yeah, Amd fixed up their firmwares and spiltted some firmwares depending on hw revision...

Comment 3 R Ghetta 2019-03-03 09:25:13 CET

With the new firmware package both 4.14.89 and 4.14.100 work.
The same with 4.18.20 from backports.
Thanks
