The system immediately res= umes after every suspend attempt. Hardware: - CPU/Platform: Intel Lunar Lake - Bluetooth device: btintel_pcie at PCI 0000:00:14.7 - iGPU: Intel Arc 140V (xe driver) Software - Kernel: 6.19.13-arch1-1 - Distribution: EndeavourOS (Arch-based) - Desktop: KDE Plasma (Wayland) - Sleep state: s2idle only (mem_sleep shows [s2idle], no S3/deep) Reproduction 1. Boot system with btintel_pcie loaded 2. Run: systemctl suspend 3. System immediately wakes up; suspend never enters sleep state Kernel log (relevant excerpt) kernel: PM: suspend entry (s2idle) kernel: btintel_pcie 0000:00:14.7: PM: pci_pm_suspend(): btintel_pcie_sus= pend [btintel_pcie] returns -16 kernel: btintel_pcie 0000:00:14.7: PM: dpm_run_callback(): pci_pm_suspend returns -16 kernel: btintel_pcie 0000:00:14.7: PM: failed to suspend async: error -16 kernel: PM: Some devices failed to suspend, or early wake event detected kernel: PM: suspend exit systemd-sleep: Failed to put system to sleep. System resumed again: Devic= e or resource busy Workaround Manually unloading the module before suspend allows sleep to succeed: modprobe -r btintel_pcie && systemctl suspend Expected behavior btintel_pcie should successfully suspend alongside the rest of the system during s2idle, or yield gracefully so the suspend proceeds without it. Notes /sys/power/mem_sleep reports [s2idle] only (no deep/S3), consistent with Lunar Lake's lack of S3 support. The issue is reproducible 100% of the time with the module loaded. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are the assignee for the bug.=
