Result of `sudo acpidump > acpi.log` attached. As for USB issues:
1. I sometimes experience bad contact to my iPhone when I charge it using a USB port. This seems to be a physically bad contact to me, however, but I cannot tell for sure. 2. Another issue is that after a USB thumb drive has been unmounted via the `unmount` command, the written data may be yet in the process of being transferred, so simply taking the drive out immediately after unmounting would probably damage the file system or the drive itself or both. I need to say `udisksctl power-off -b /dev/sdb` and wait for termination to make sure that the device is really safe to unplug. As for wake-up, the laptop seldom refuses to wake up and freezes instead. I simply gave the issue as an example of what goes wrong (there are dozens of such small issues). ** Attachment added: "Result of `sudo acpidump > acpi.log`." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890467/+attachment/5399096/+files/acpi.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890467 Title: wmi_bus wmi_bus-PNP0C14:00: WQBC data block query control method not found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890467/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
