Hi Michel,

So summarizing wi= th Linux kernel 4.17-rc6 on Ubuntu 18.04 using AMD RX 460/RX 550 I am not a= ble to enter X.
The same system with AMD Radeon R7 240 not only e= nters X as also runs the OpenCL kernel that RX 460 / RX 550 are unable to r= un for all the kernels that I have tested.
Could this also be a M= esa issue, regarding OpenCL on RX 460?

Regards,
Lu=C3=ADs

Hi Michel,

I will have = to check previous rc releases of 4.17 to see if it wasn't already happe= ning, before trying any possible git bisect.
As an update I can s= ay that an AMD Radeon R7 240 works fine on the same system with the same ke= rnel and I am able to run the OpenCL kernels, that I couldn't with RX 4= 60/RX 550.

Can you isolate which change introduced this new issue with git bise= ct?
