Please enable btusb autosuspend during test. This is what happened: [25781.865975] PM: suspend entry (deep) System is about to suspend to deep (S3),
[25782.016682] pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -16 [25782.016691] dpm_run_callback(): pci_pm_suspend+0x0/0x130 returns -16 [25782.016694] PM: Device 0000:00:14.0 failed to suspend async: error -16 [25782.920799] PM: Some devices failed to suspend, or early wake event detected But the xHC (USB controller) wakes up early, so the system aborted S3, [25782.922906] usb usb1-port7: status 0103 change 0004 The one wakes xHC up is btusb, which is woken up by BLE events, [25783.167977] PM: suspend exit [25783.168050] PM: suspend entry (s2idle) System tries to suspend again, via s2idle. This happens more than once. [25842.804908] PM: suspend entry (deep) [25842.804912] PM: Syncing filesystems ... done. [25842.834864] Freezing user space processes ... (elapsed 0.002 seconds) done. [25842.837207] OOM killer disabled. [25842.837208] Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done. [25842.838619] Suspending console(s) (use no_console_suspend to debug) Finally it suspends successfully, but both btusb and ath10k_pci devices fail to work: [25843.579504] ath10k_pci 0000:02:00.0: Refused to change power state, currently in D3 [25844.303534] usb 1-7: device descriptor read/64, error -71 Most devices' .resume() and .suspend() callbacks rely on full system suspend/resume works successfully. This assumption breaks when the first system suspend fails, which is cause by the BLE event. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799988 Title: Missing wifi and bluetooth after sleep on XPS 9370 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1799988/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
