dmesg with backtrace

Currently https://cgit.freedesktop.org/~agd5f/linux/tree/?h=drm-next-5.1-wip is totally broken at least for raven 2400g apu.

4.20.5 works pretty well on this machine.

Dmesg with backtrace attached.

Dear AMD developers: it would be bad if drm-next-5.1-wip code in its current state went into mainline, please review and fix.

another dmesg with warning backtrace before GPF

Previous dmesg was from a build containing a patch to make shut up the warning which hasn't been fixed for months ...

No, sadly it doesn't help.
Additional observations:
If amdgpu is built as module the system boots without graphics, but networking and ssh are working, however it's impossible to reboot the system, it just hangs after issuing "reboot".
If amdgpu is built-in (with embedded raven* firmware blobs) the system just hangs with black screen, no network.

Reverting just the -msse2 commit on top of drm-next works fine for me.
