Package: linux-image-6.12.73+deb13-amd64 Version: 6.12.73+deb13-amd64 Severity: important
Dear Debian Kernel Team, I would like to report several boot and power-management issues observed after installing kernel version 6.12.73+deb13-amd64 on older Ivy Bridge hardware. System Information Motherboard: ASUS Sabertooth Z77 CPU: Intel Core i7-3770K (Ivy Bridge) Firmware: UEFI (legacy-compatible board) Distribution: Debian (stable branch) Architecture: amd64 GPU: NVIDIA (proprietary driver installed) Problem Description After upgrading to kernel 6.12.73+deb13-amd64, the system exhibits multiple boot and runtime problems: Boot failures occur intermittently with the following messages: EFI stub: ERROR: Failed to decompress kernel EFI stub: ERROR: efi_stub_entry() failed During successful boots, ACPI-related errors appear in dmesg involving unresolved symbols and SATA controller initialization (_GTF/DSSP related messages). System suspend behavior is unreliable: *When placing the system into sleep mode, the computer immediately wakes without user interaction. Overall system startup appears noticeably slower compared to previous kernels. Expected Behavior The system boots reliably without EFI stub errors, ACPI warnings, or unexpected wake events during suspend. Observed Behavior Kernel 6.12.73+deb13-amd64 causes intermittent boot loader failures, ACPI-related warnings, and unreliable suspend functionality on this hardware. Workaround Booting an earlier kernel (e.g., 6.12.69+deb13-amd64) restores normal behavior and eliminates the EFI decompression failure and sleep issues. Additional Notes Reinstalling the kernel temporarily resolved the EFI decompression error, suggesting either a regression affecting older firmware platforms or sensitivity during installation on legacy UEFI implementations. Please let me know if additional logs, dmesg output, or hardware information would be helpful for debugging. Best regards, Donovan -- Secured with Tuta Mail: https://tuta.com/free-email
