Would it be possible to do some experiments/debugging: - Can you reproduce the issue with 6.1.85 upstream itself? - If so can you try the current 6.1.87 (as of time of writing), does the issue reproduce there? - If it's still happening, can you try to bisect the changes between 6.1.76 and 6.1.85 to identify the culprit? Regards, Salvatore

Hi Salvatore, It had been a while (like 10+ years) since I built a kernel from source, so this guide was very welcome, and the "make bindeb-pkg" target is great: https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s-kernel-org-package It looks like the problem is present in the upstream kernel, I have so far reproduced it with: - linux 6.1.85 - linux 6.1.87 I'll start building previous patch releases until I find one that works, but it's slow going! Cheers, Jeremy

Hi Salvatore, I've finished bisecting and the version that seems to introduce the breakage is 6.1.83. I tested the following upstream kernels: - linux 6.1.80 => OK - linux 6.1.82 => OK - linux 6.1.83 => BUG - linux 6.1.85 => BUG - linux 6.1.87 => BUG I looks like 6.1.83 introduced quite a few bluetooth changes, so I don't know which one caused the breakage: https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.83 What else can I do to assist? Cheers, Jeremy
