BSOD with SYSTEM_THREAD_EXCEPTION_NOT_HANDLED error code caused by atikmdag.sys when installing driver on Win10 64-bit system with AMD RADEON RX VEGA(56 or 64) and AWARD bios (CPU, motherboard, memory and other don't matter). Problem exists in all driver versions beginning from AMD blockchain drivers and ending by current 18.5.1 driver.
I think all systems with AWARD bios are affected by this (can confirm myself on Gigabyte GA-MA770-UD3(any bios version) and Biostar TF570 SLI(any bios version)), see this thread on reddit: https://www.reddit.com/r/Amd/comments/6x0t98/rx_vega_64_not_working_on_pci_express_20/
There is nothing common in systems mentioned there, except that all have AWARD bios. This issue is not caused by pcie-e version (I have systems with legacy AMI BIOS, pci-e 1.0 and 2.0, and no issues with drivers). Bug report has already submitted to AMD, but I think this problem needs more attention. If anyone has same issue, please confirm.
