I have found lots of kernels at your home repo home:tiwai :) Are they OK for testing? It seems to me they are not stable versions (git commit?). Anyways, I went ahead and tested the following ones: kernel-default-5.12.13-1.1.g74bd8c0.x86_64 kernel-default-5.11.16-1.1.ge06d321.x86_64 kernel-default-5.10.16-1.1.g11381f3.x86_64 and I got the same error as before for all of them :-(
