[545.29.06-18.1]Flip event timeout error on startup, shutdown and sometimes suspend. Wayland unusable

Graphics / Linux Linux
64

Still happening on 610.43.02 with an RTX 3060 on KDE Plasma 6 / Wayland. Adding my data points in case they help — especially a couple that might narrow down the root cause.

Symptom

On every shutdown/reboot the machine frequently fails to power off completely (~19 out of 20 attempts). systemd finishes the whole shutdown (The system will power off now!), the screen loses signal and USB powers down, but the machine never reaches the final power-off: case fans and RGB stay on and I have to force-off with the power button. It is intermittent (~1 in 20 powers off correctly). The kernel log always shows the flip timeout right as the Wayland compositor releases the GPU.

System

  • GPU: NVIDIA GeForce RTX 3060 (GA106), ASUS ROG Strix RTX 3060 V2 OC 12GB [10de:2504 / 1043:8818]
  • Driver: 610.43.02 — reproduced with both the open kernel module and the proprietary/closed module
  • OS: CachyOS (Arch-based), kernel 7.0.11 (also on 6.18.x LTS)
  • Desktop: KDE Plasma 6, Wayland (kwin_wayland)
  • CPU/Board: Ryzen 9 5900X, ASUS PRIME B550M-A (BIOS 3636, latest)

Kernel log at shutdown (always the same pattern)

systemd-logind: The system will power off now!
nvidia-modeset: WARNING: GPU:0: Lost display notification (0:0x00000000); continuing.

Data points that might help

  1. The hang only happens when shutting down from the running Wayland session. Booting to multi-user.target (no graphical session) and running poweroff powers off cleanly 3/3 times. So the trigger is the GPU teardown of the Wayland compositor (kwin_wayland) during shutdown, not the platform/firmware.

  2. Setting nvidia_drm.fbdev=0 makes the “Flip event timeout” messages disappear completely, but the shutdown STILL hangs. This strongly suggests the flip timeout is a concurrent symptom, not the root cause of the hang — the actual hang is in the GPU teardown itself. At shutdown, kwin_wayland burns ~3 min of CPU and logs atomic commit failed: Permission denied before the hang.

  3. Unloading the NVIDIA modules right before poweroff (a /usr/lib/systemd/system-shutdown script with modprobe -r nvidia_drm nvidia_modeset nvidia_uvm nvidia) does not help either.

Ruled out (none of these fixed it)

  • BIOS update to latest + ErP Ready (S4+S5) enabled
  • acpi=force / ACPI tweaks
  • USB wakeup disabled for all controllers (/proc/acpi/wakeup)
  • NVMe APST (nvme_core.default_ps_max_latency_us=0)
  • KDE session restore disabled (loginMode=emptySession)
  • NVreg_PreserveVideoMemoryAllocations=0
  • Switching between the open and the proprietary kernel module (both hang identically)
  • nvidia_drm.fbdev=0 (removes the timeout messages but not the hang)

Bug report log attached. Happy to test patches or gather more logs.
