5.4-aplha 2 does not boot to either Firepro nor SI card.

5.4-alpha 2 without DRM boots fine to Firepro and Logitech mouse is still working-:)
Keep up the great work.

Hi All,

Great news!

Alex released a new DRM patch because of the boot issue with Radeon NI graphics cards yesterday. I compiled the latest Git kernel with this patch today. After that I could boot this kernel with my Radeon NI graphics cards without any problems!
