Subject: PROBLEM: Issue With Radeon graphics With Lenovo Laptop G50-80

Hi,

I recently decided to try out the latest Linux kernel release v4.11, I
compiled and installed it, while booting the latest kernel; the screen
freezes.There is no response from the kernel, the only option I have
is to turn off and start it again.

I tried booting the kernel using debian recovery option, when i tried
to load the radeon module here is the error i got,

anilnair@...lnair-lenovo:~$ dmesg | grep radeon
[    1.255633] [drm] VGACON disable radeon kernel modesetting.
[    1.255698] [drm:radeon_init [radeon]] *ERROR* No UMS support in
radeon module!
[   22.261475] [drm] VGACON disable radeon kernel modesetting.
[   22.261500] [drm:radeon_init [radeon]] *ERROR* No UMS support in
radeon module!
anilnair@...lnair-lenovo:~$ sudo modprobe radeon
[  716.704231] [drm] VGACON disable radeon kernel modesetting.
[  716.704267] [drm:radeon_init [radeon]] *ERROR* No UMS support in
radeon module!

I am attaching the relevant details, Please let me know if any further
information is needed.
