Hi! Some more experimentation has shows that this kernel, on the same hardware, doe snot show the buggy behavior:
ii linux-image-6.0.0-6-amd64 6.0.12-1 amd64 Linux 6.0 for 64-bit PCs (signed) I don't know if there are any releases in between this and the kernel mentioned in the original report that are worth testing. Best, Tobias
