Hi,
My PC has [AMD/ATI] Kaveri [Radeon R7 Graphics] card.
When I add radeon.cik_support=0 amdgpu.cik_support=1 in grub.cfg boot line,
the PC can't boot, it's screen will dark, the keyboard also can't use.
I find the kernel NULL pointer infos in the kern.log after I power restart
the PC which not use amdgpu.cik_support=1:
The following infos copy from /var/log/kern.log:
