Package: linux-image-6.17.11+deb14-amd64 Version: 6.17.11-1 Severity: important X-Debbugs-Cc: debian-amd64@lists.debian.org User: debian-amd64@lists.debian.org Usertags: amd64 Dear Maintainer, I had my Debian testing desktop reboot after an unattended upgrade where the kernel was updated from linux-image-6.17.9+deb14-amd64 to linux-image-6.17.11+deb14-amd64. After reboot overnight, I found the machine unresponsive in the morning. Rebooting revealed many successive kernel oops in amdgpu. Oops text below. The GPU in use is an AMD Radeon R9 270X ("Curacao XT"), from the GCN 1.0 generation. I _am_ using the following argument on the kernel command line to gain some performance: amdgpu.ppfeaturemask=0xffffffff This kernel oops was not occurring in kernels up to and including 6.17.9 (Debian-packaged). I have not tried to boot 6.17.11 without the amdgpu.ppfeaturemask=0xffffffff kernel command-line argument to see if the oops still occurs. I did find that there was some work done on amdgpu in November: https://lists.freedesktop.org/archives/amd-gfx/2025-November/133356.html I don't know enough to know whether that work could cause this kernel oops. Downgrading back to 6.17.9 has eliminated the kernel oops.
