========= System ===============
- CPU: AMD Ryzen 7 5700G (Renoir APU)
- Motherboard: ASUS ROG STRIX B450-I (BIOS 5901)
- OS: EndeavourOS (Arch-based)
- Kernel: 6.12.63-1-lts
- Mesa: 25.3.4
- Display: Wayland (GNOME Shell 49.3)
========== Bug ===================
First suspend/resume cycle works correctly. Second suspend hangs with cursor update failures. PC fan keeps running.
========== Logs in Attachement ===================
- after-resume-1_with-612-kernel.log
- after-failed-second-suspend_with-612-kernel.log
- suspend-log-0x1C_with-618-kernel.txt
========== Key Errors ===================
- xhci_hcd 0000:01:00.0: xHC error in resume, USBSTS 0x401, Reinit
- gnome-shell: Cursor update failed: drmModeAtomicCommit: Invalid argument
- System hangs at "Performing sleep operation 'suspend'"
========== Update ======================
Testing with Kernel 6.18 shows:
- New error: "asus_wmi: failed to register LPS0 sleep handler" (not present in 6.12 LTS)
- amdgpu.dcfeaturemask=0x1C fixes cursor errors in 6.12 LTS but has NO effect in 6.18
- Suspect: ASUS board-specific LPS0 handler failure interferes with suspend
- Hardware: ASUS ROG STRIX B450-I GAMING (BIOS 5901)
====== Workaround =============
Use suspend-to-disk (hibernation) instead of suspend-to-RAM.
