Update 2026-07-24 — 2 additional occurrences, new kernel and firmware do not fix the issue
The crash has now occurred 2 times today, all with an identical signature. Occurrences: 2026-06-29 09:53:56 (original report) 2026-07-24 08:48:15 (second occurrence) 2026-07-24 16:40:08 (third occurrence — same session, different Chrome PID) New kernel and firmware installed today did not help: This morning I ran sudo apt upgrade, which installed: Kernel 7.0.0-28-generic (previously 7.0.0-27) linux-firmware-amd-graphics 20260319.git217ca6e4-0ubuntu3.1 (previously 0ubuntu3, firmware files updated Jun 25) After rebooting into the new kernel and firmware, the crash occurred again within the same session — twice. The crash pattern is identical across all four occurrences: Chrome GPU process submits an invalid address to the GPU (PERMISSION_FAULTS: 0x3, client SQC (data), UTCL2 page fault on gfxhub) gfx_0.1.0 ring times out with gnome-shell as a victim process Ring-level reset fails → full MODE2 GPU reset required gnome-shell loses its GPU context and exits with SIGABRT Entire GNOME/Wayland session is lost; GDM login screen appears On the third occurrence (kernel 7.0.0-28), a compute ring (comp_1.1.0) also timed out but its reset succeeded — the gfx_0.1.0 reset still failed and required the full GPU reset. Fault addresses seen (all PERMISSION_FAULTS: 0x3): 0x000000003f919000 (Jun 29) 0x0000400040004000 (Jul 24 08:48 — suspicious repeating pattern) 0x000049aa22454000 (Jul 24 16:40) Saved artefacts: AMD GPU coredump from 08:48 crash: amdgpu_coredump_20260724_085213.bin (available on request) Full journalctl -b output covering all three Jul 24 events available on request System: AMD Granite Ridge iGPU (1002:13c0), kernel 7.0.0-28-generic, Mesa 26.0.3, Chrome 150.0.7871.186, Ubuntu 26.04 Chrome was in use (GitLab in browser tab) during all crashes. No other GPU-intensive workload was running. The crash does not require a Teams/video call — ordinary browser use is sufficient to trigger it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2158614 Title: amdgpu: Granite Ridge iGPU gfx ring timeout after Chrome GPU page fault causes gnome-shell SIGABRT and session loss To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2158614/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
