Several GPU warnings on Arc A370M
When booting a system with an Arc A370M GPU, several warnings are printed to dmesg and the GPU seems to run with horrible performance, sometimes to the point where the integrated GPU is significantly faster. The GPU also seems to consume at least 10W even when completely idle.
The kernel is version 6.2.0-rc6, compiled locally from commit 0136d86b78522bbd5755f8194c97a987f0586ba5.
One of the warnings:
