Somehow it affected later amd iommu device resume which is controlle= d by kfd resume. This workaround is to gate vcn block immediately when ring test passed. It can fix the suspend/resume hung issue. Hi kolAflash, Please help check the WA in your setup. I will continue working on root cau= se. thanks!
