We would need more context information on those. Can you followup to this bug with the information gathered on HW when filling 'reportbug kernel' please? (I understand you redacted above some information). Is this a regression from a previous 6.12.y kernel? Which was the last one which worked? If it worked before, can you please bisect the issue? Doing so would involve compiling a couple of kernels. Assume 6.12.88-1 was okay and so 6.12.90-2 was the first Debian kernel which exposes the issue, then proceed as follows: git clone --single-branch -b linux-6.12.y https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git cd linux-stable git checkout v6.12.88 cp /boot/config-$(uname -r) .config yes '' | make localmodconfig make savedefconfig mv defconfig arch/x86/configs/my_defconfig # test 6.12.88 to ensure this is "good" make my_defconfig make -j $(nproc) bindeb-pkg ... install the resulting .deb package and confirm problem does not exist # test 6.12.90 to ensure this is "bad" git checkout v6.12.90 make my_defconfig make -j $(nproc) bindeb-pkg ... install the resulting .deb package and confirm problem exists With that confirmed, the bisection can start: git bisect start git bisect good v6.12.88 git bisect bad v6.12.90 In each bisection step git checks out a state between the oldest known-bad and the newest known-good commit. In each step test using: make my_defconfig make -j $(nproc) bindeb-pkg ... install, verify if problem exists and if the problem is hit run: git bisect bad and if the problem doesn't trigger run: git bisect good . Please pay attention to always select the just built kernel for booting, it won't always be the default kernel picked up by grub. Iterate until git announces to have identified the first bad commit. Then provide the output of git bisect log In the course of the bisection you might have to uninstall previous kernels again to not exhaust the disk space in /boot. Also in the end uninstall all self-built kernels again. Again the 6.12.88 above is hypotetical, would need to be the last one working for you. Regards, Salvatore
