I’m coming from bug 2121706. I’ve been troubleshooting the same “Meteor Lake + i915” GPU hangs on Ubuntu 24.04 (Noble) and Ubuntu 25.04 (Plucky). The hallmark is:
i915 ... [drm] *ERROR* GT0: GUC: TLB invalidation response timed out for seqno ... Sometimes it escalates to GPU HANG / context resets. In my case setting i915.enable_guc=0 causes the system to not boot past GRUB (black screen / no login). So I can’t use that workaround suggested in other bugs. Hardware Laptop: Lenovo ThinkBook 14 G7 IML (Model 21MR) GPU: Intel Meteor Lake-P (PCI ID 8086:7dd5, rev 08) BIOS/UEFI: P3CN48WW (2025-03-27) OS / kernels tested Ubuntu 24.04.2 LTS with OEM/HWE kernels (e.g. 6.11.0-1025-oem; previously also 6.8/6.14 variants) Ubuntu 25.04 (Plucky) with 6.14.0-29-generic (also saw 6.14.0-27) Microcode/firmware current (fwupdmgr shows no newer Lenovo updates for this device) Graphics stack status (important note about PPA) Initially I had Oibaf PPA enabled. Per Ubuntu dev guidance I removed it and downgraded DRM userspace back to Ubuntu stock: sudo add-apt-repository ppa:oibaf/graphics-drivers -r sudo rm -f /etc/apt/sources.list.d/oibaf-ubuntu-graphics-drivers-*.sources sudo apt update # Downgrade back to Ubuntu versions (both amd64+i386 where applicable): sudo apt install --allow-downgrades \ libdrm2=2.4.124-2 libdrm2:i386=2.4.124-2 \ libdrm-amdgpu1=2.4.124-2 libdrm-amdgpu1:i386=2.4.124-2 \ libdrm-intel1=2.4.124-2 libdrm-intel1:i386=2.4.124-2 \ libdrm-nouveau2=2.4.124-2 libdrm-radeon1=2.4.124-2 \ libdrm-common=2.4.124-2 apt-cache policy now shows candidates only from official Ubuntu repos. The issue still reproduces without Oibaf. Kernel parameters tried & results i915.enable_psr=0 — kept disabled (PSR off). i915.enable_dc=0 — tested both on/off; doesn’t eliminate the hangs. intel_iommu=igfx_off — helps avoid VT-d/DMAR side noise; not a complete fix. i915.enable_guc=0 — system does not boot past GRUB on this machine. How to reproduce (for me) Most likely during video playback / video conferencing (YouTube, calls). Sometimes under heavy desktop usage (Wayland/GNOME). On Plucky 6.14 and Noble OEM 6.11 it can happen within a normal session. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2085434 Title: i915 GPU hangs on Intel Meteor Lake [*ERROR* GT0: GUC: TLB invalidation response timed out for seqno ...] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2085434/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
