Pair some Bluetooth BLE device. Open a terminal and run `dmesg -w` to make sure Bluetooth is receiving advertisement events and repeatedly printing: Bluetooth: hci0: advertising data len corrected ... 2. Turn off dim display/blank screen on idle in Settings 3. Shorten long idle suspend time to 2 minutes by: $ gsettings set org.gnome.settings-daemon.plugins.power \ sleep-inactive-ac-timeout 120 4. Idle wait for 2 minute and let system suspend. 5. Resume after 20 seconds suspend or so. [Expected result] System resumes normally. [Actual result] * Screen lighted up, sent to GDM greeter as expected, but UI freeze when pressed ENTER to submit filled account name/password. * No console switch is possible. * Kernel alive because rescue magic key is the only way to escape. * The last line in syslog is: kernel [...] PM: suspend entry (deep) * When Bluetooth is rfkilled, this issue is not happening. When Bluetooth has never paired to BLE devices, this issue is no happening, either. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.9 Architecture: amd64 Dependencies: DistributionChannelDescriptor: # This is the distribution channel descriptor for the OEM CDs # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-somerville-bionic-amd64-20190418-59+beaver-osp1-loras+X21 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2019-12-02 (3 days ago) InstallationMedia: Ubuntu 18.04 "Bionic" - Build amd64 LIVE Binary 20190418-12:10 Package: linux-firmware 1.173.12 PackageArchitecture: all ProcVersionSignature: Ubuntu 5.0.0-1028.32-oem-osp1 5.0.21 Tags: bionic Uname: Linux 5.0.0-1028-oem-osp1 x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1855235/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
