What ASIC are you using ? I also tested with gfx8 ASIC and haven't observed any issues with resume. Did you update the firmware for this ASIC to latest #
The GPU is an RX460 "POLARIS11 0x1002:0x67EF 0x1682:0x9460 0xCF", with the latest firmware from the kernel git, you can see the details from https://bugs.freedesktop.org/attachment.cgi?id=140383 uploaded earlier.
We have only minor differences but I can't reproduce it. Maybe the resume failure is indeed due the eviction failure during suspend. Is S3 failure is happening only when you switch to CPU update mode ?
