after bios update to 1.45 resume from suspend failed. it didn't wake up or write anything to the logfiles.
(only a blank screen / no ssh )
resume worked fine with 1.32. tested with fedora 29 and arch linux.
Solved! Go to Solution.

have found a workaround that works for me now.
disable bluetooth and amd vmm
before suspend unload ath10k_pci and ath10k_core
remove some udev rules for powersaving, discharge rate is now around 7W.
arch linux / kernel 4.20rc2 / boot parameter: iommu=soft amdgpu.ppfeaturemask=0xffffbfff

archlinux with kernel 4.18.12 works very good. (no need for works around - resume works after 8h and longer)
after kernel 4.18.12 resume is broken.
kernel linux-next 051218 works but after resume display is black - need to type brightness key. (testing)
kernel boot still needs: iommu=soft

Same Problem with 1.46 and Arch Kernel 4.19.4 - Standby and hybrid standby both don't come back. Black Screen - sometimes with frozen Mousepointer.
As kenduro pointed out unloading the modules works.

did you try kernel 4.18.11 ?
i try ubuntu 18.10 with 4.18.11 and no problems with suspend.
arch linux with a newer kernel suspend still broken. hope that maybe 4.21 get a fix.
not sure that this fix will help:
