Hi All,

Here is the alpha5 of kernel 6.17 for X1000 and e5500 machines (X5000/20, X5000/40, Mirari, and QEMU VMs).

I created kernels with and without the drm-next-2025-07-30 updates [1] because of the issue with the Radeon graphics framebuffer device #15. [2]

Download and further information: https://github.com/chzigotzky/kernels/releases/tag/v6.17.0-alpha5

Please test both kernels.

Thanks,
Christian

I tested both kernels on my X1000 today and I can definitely confirm, 
that the issue is somewhere in the commit drm-next-2025-07-30 updates [1]

The Radeon graphics framebuffer doesn't work with the kernel with the 
drm-next-2025-07-30 updates [1]. Without these updates, the framebuffer 
works.
