Config-4.20-rc6

Kernel 4.20.0-rc5 starts fine and is stable on my system.
With the same .config I get kernel 4.20.0-rc6 in dmesg the error given above: "mc: Failed to load firmware" amdgpu / polaris11_k_mc.bin "".
The GPU will not initialize and Xorg will not start.

I found this e-mail:
https://lists.freedesktop.org/archives/amd-gfx/2018-December/029175.html

The problem is, in Linux firmware there is no polaris11_k_mc.bin.
There is only one polaris11_k_smc.bin.

My question: is this a typo or will polaris11_k_mc.bin be delivered soon?

Thank you for your attention

The patch was sent to linux-firmware a couple of weeks ago.  It should land any day now.  In the mean time you can grab it here:

Thank you for the quick hint:
Now the system starts without problems.
