Package: linux Version: 6.12.48+deb13-1 Severity: serious Tags: upstream regression ftbfs Control: affects -1 + src:linux
Dear Maintainer, The newer kernel image, **6.12.48+deb13-amd64**, causes a black screen during boot on a Sony Vaio VPCCW1S1E laptop. The issue is a **regression**, as the previous stable kernel, **6.1.40-amd64, works perfectly** with the open-source Nouveau driver. ### Hardware Affected * **Laptop Model:** Sony Vaio VPCCW1S1E * **Graphics Card:** **NVIDIA GT216M (GeForce GT 230M)** ### Diagnostic Information When booting the 6.12.48+deb13 kernel, the system fails to initialize any display output, including virtual consoles (TTYs), preventing a user from reaching the login prompt. By checking the system logs from a failed boot, the following critical error message was found, indicating a driver crash related to the GPU's core or power management: nouveau 0000:01.00.0: gr: TRAP_PROP TP1 - 00000040 [RT-FAULT] ### Troubleshooting Attempts All attempts to fix the issue via kernel parameters on the 6.12.48 kernel have failed: 1. Adding **'nouveau.modeset=0'** 2. Adding **'nouveau.runpm=0'** (disabling runtime power management) 3. Blacklisting the Nouveau driver completely. The only way to boot the 6.12 kernel is by using the **'modprobe.blacklist=nouveau'** or **nomodeset=1** parameter, which forces a generic VESA driver with poor resolution and no acceleration. --- end of report ---
