Is this a 32-bit kernel ?
Is amdkfd compiled ?
The kconfig file is attached in the original email. From it, it is
32-bit kernel. I don't find AMDKFD in config file. Could you help me
to check it?
Best Regards,
Huang, Ying

Are you using some specific distribution or h/w ?
I'm compiling that commit with the Kconfig you sent me, installing it on a
Debian 7.7 32-bit installation inside VirtualBox, and it doesn't even boot.
Must I use a native installation ?

I tried also running it more or less like you do, in qemu, but I don't get past
the line:
Booting the kernel.
I'm not used to working with 32-bit kernels, as amdkfd doesn't support that at
all. Could you give me some help to make the kernel run at all ?
