Let us trace the issue one by one.
IB test fail:
This should be regression issue on 4.18, you can bisect the kernel patches.
Fix IB test fail first.

Thanks for your interest in this issue. Actually this is a multiple
issue... not only the IB ring test is failing... as I am having quite
some trouble getting the cards SAPPHIRE RX 550 4GB on a Tyan S7025 and
SAPPHIRE RX 460 2GB on a TYAN S7002 to work, both systems using same
Ubuntu 18.04 with vanilla kernel.
*1. May you also test earlier kernel? v4.17 or v4.16.*
I've tested kernels v4.17.5 and v4.16.6 with same system and both are
able to pass the IB ring test and system boots into X using NVIDIA as
the display connected card.
dmesg log attached for kernel 4.17.5, file
*2. May you test the issue only with amdgpu?*
- I've tested on a TYAN S7002 system with a single SAPPHIRE RX 460
2GB, on-board VGA enabled and used as primary display.
Kernel v4.18-rc4 fails the IB ring test, system is able to enter X
through the on-board VGA.
dmesg log attached for kernel 4.18-rc4, file
- Same TYAN S7002 system, but now with on-board VGA disabled and using
RX 460 as display connected card.
Kernels v4.17.5 and v4.16.6 are able to pass the IB ring test, but GPU
hangs before entering X. Don't have logs for these yet.

test on power-up
Issue remains in kernel 4.18-rc4 using SAPPHIRE RX 550 4GB.
Logs follow attached.

I've tried kernel 4.18-rc2 on a system with a NVIDIA GTX 1050 Ti
and an AMD RX 550 4GB and the RX 550 card is failing the IB ring test.
[ 5.033217] [drm:gfx_v8_0_ring_test_ib [amdgpu]] *ERROR*
amdgpu: ib test failed (scratch(0xC040)=0xFFFFFFFF)
[ 5.033264] [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* amdgpu:
failed testing IB on ring 6 (-22).
Please see the attached log.
