I've been facing freezes for many days on Ryzen1600+RX560. I have tried bios,
kernel, mesa updates, kernel parameters: "processor.nocst=1 iommu=pt
amggpu.vm_update_mode=3", but it didn't help. Finally I've tried kernel param
ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 and it does the trick. No
freezing anymore.
