I applied windows 10 updates today, and after the reboot, none of the AMD Radeon software drivers will load properly. I have used the removal tool, reinstalled the drivers that were previously working, re-installed 12.1, and have installed latest drivers as well (all with a cleanup between attempts). None of the drivers will initialize the graphics card and I have to fall back to the standard Windows 10 VGA driver. If I try to run the AMD utilities, it says there isn't a card installed. Driver installation completes without any problems/errors. Device manager reports Code 43 (Windows has stopped this device, etc...)
Radeon RX570 card
In the driver Events section, I see an event that the PCI link was not migrated due to "partial or ambiguous match"
Device PCI\VEN_1002&DEV_67DF&SUBSYS_C5701682&REV_EF\4&2f1c4782&0&0018 was not migrated due to partial or ambiguous match.
Last Device Instance Id: PCI
Followed by 4 more entries:
(Driver Management has concluded the process to add Service amdkmdap...) with a status 0
Driver Management has concluded the process to add Service amdkmdag for Device Instance ID PC with a status 0
Driver Management has concluded the process to add Service AMD External Events Utility for Device Instance ID PCI wit a status of 0
Driver Management concluded the process to install driver c0322096.inf_amd64_7ff7d53c3793b9e4\c0322096.inf for Device Instance ID PCI with a status of 0
I'm not sure if these messages are relevant to the current issue (but I suspect so)
This has taken my home office/work system down for 2 hours today, and impacts other processes that I have running on this machine, therefore is costing me $$ until the AMD drivers are functional again.
Is there any indication of why this has happened, or what the workaround is currently?
