My X13 Gen 4 AMD has essentially the same GPU:
amdgpu0 at pci5 dev 0 function 0 "ATI Phoenix" rev 0xdd
drm0 at amdgpu0
amdgpu0: msi
amdgpu0: IP DISCOVERY GC 11.0.1 12 CU rev 0x09

Hibernate "works" on this machine but:
* After unhibernate, the framebuffer is filled with random crap; we
probably need to clear it in the driver somewhere.
* After unhibernate, qwx(4) is somewhat hosed. It works, but if you
try to down the interface, it hangs. It seems that the "head
pointer" for one of the ring gets corrupted and this makes the
driver go into an infinite loop. I can break into that loop using
CTRL-ALT-ESC though (sysctl ddb.console=1). I'm investigating this
issue.
* Sometimes I get a kernel that always produces a
"unhibernate failed: original kernel changed"
message.
