Public bug reported:
Tested on 2 computers (towers : computers "A" and "B"). I can't
reproduce it on a laptop (computer "C").
Steps :
- plug the usb HUB (in my case with a mouse plugged on it)
- power on the computer
- suspend (to RAM)
=> The computer (tower) will fail to suspend and either be frozen (no video on
my computer "A") or "resume" to the lock screen of gnome (the current computer
"B" used to report the bug). The laptop "C" suspend normaly.
- power off
- unplugg the usb HUB
- power on the computer
- plug the usb HUB
- suspend (to RAM)
=> The computer will suspend normaly (computers "A", "B" and "C").
Revelating part of the dmesg log file.
