System suspended before kernel suspends all tasks. Lenovo ThinkPad T460 Status in linux package in Ubuntu: Incomplete Bug description: The same as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825636. kaihengfeng closed that one "Because there's no response from the original bug reporter." and asked to file a report for all devices affected, so here I am, duplicating the report. On Ubuntu MATE 18.04, as well as after the update to 20.04, the battery drains about 2% per hour of sleep (if I just close the lid). $ cat /sys/power/mem_sleep s2idle [deep] tlp was initially installed on my machine. However, this behaviour also occurs if I $ sudo apt purge tlp acpi-call-dkms && sudo reboot now also, it occurs when booting from a freshly made MATE 20.04 live usb stick, so TLP shouldn't be the culprit. All the log files look in all relevant aspects similar to what was reported in the old report. I'm happy to provide log files from my machine, if any are necessary.
