Package: linux-image-7.1.8+deb13-amd64 Version: 7.1.8-1~bpo13+1 Severity: important
Dear Maintainer, After upgrading to kernel 7.1.8, the system freezes when Alt+Tabbing out of fullscreen games (tested with Fallout Shelter via Steam/Proton). dmesg shows: amdgpu 0000:0a:00.0: [drm] *ERROR* [CRTC:422:crtc-0] flip_done timed out amdgpu 0000:0a:00.0: [drm] *ERROR* flip_done timed out amdgpu 0000:0a:00.0: [drm] *ERROR* [CRTC:422:crtc-0] commit wait timed out Hardware: AMD Radeon RX 6600 (Navi 23), Ryzen 7 5700X, Gigabyte B550 AORUS ELITE V2 (BIOS FId, 2026-08-18), 128 GB RAM. Kernel 7.1.3 works fine with same hardware and same games. The problem is a regression introduced in 7.1.8. Workaround: revert to kernel 7.1.3 and pin it via apt-mark hold. I already tried amdgpu.dcdebugmask=0x410 and it did not help. Note: currently running 7.1.3 (as shown in System Information below), because 7.1.8 is unusable due to this bug. -- System Information: Debian Release: 13.7 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 7.1.3+deb13-amd64 (SMP w/16 CPU threads; PREEMPT) Kernel taint flags: TAINT_USER, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=ru_RU.UTF-8, LC_CTYPE=ru_RU.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages linux-image-7.1.8+deb13-amd64 depends on: ii initramfs-tools [linux-initramfs-tool] 0.148.4 ii linux-base 4.12.1 pn linux-base-7.1.8+deb13-amd64 <none> pn linux-binary-7.1.8+deb13-amd64 <none> pn linux-modules-7.1.8+deb13-amd64 <none> Versions of packages linux-image-7.1.8+deb13-amd64 recommends: ii apparmor 4.1.0-1 Versions of packages linux-image-7.1.8+deb13-amd64 suggests: pn debian-kernel-handbook <none> ii firmware-linux-free 20241210-2 ii grub-efi-amd64 2.12-9+deb13u2 pn linux-doc-7.1 <none>
