Still reproducible in 2026 (Radeon HD 5650M, kernel 7.0.0, Mint 22.3 / noble). Root cause: resume runs the full UVD init, but the single ring-test window races the hardware coming out of D3; the driver gives up after one try and UVD stays dead until reboot.
Working fix (retry UVD init up to 3 times with full stop between attempts): https://github.com/ukrainer8/radeon-evergreen-fixes — ships as a DKMS package (auto-rebuilds on kernel updates), one-command install in README. Tested: stock ~50% success across 42 suspend cycles, patched 6/6. The repo also includes an automated suspend-cycle test stand if anyone wants to verify on their own Evergreen/NI card. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1865130 Title: [drm:uvd_v1_0_start [radeon]] *ERROR* UVD not responding, trying to reset the VCPU!!!
