Title:
Shutdown/reboot hang on Dell XPS 15 9550 BIOS 1.2.18+
Status in linux package in Ubuntu:
Confirmed
Bug description:
On Dell XPS 15 9550 BIOS 1.2.18+, shutdown/reboot job is delayed for
several seconds in Ubuntu kernel. After shutdown screen appears and
all shutdown sequence had been done, the power LED turns off; however
the front LED is flashing in orange for several seconds and the system
finally turns off. Rebooting is also not working: front LED flashes in
orange and the system just turns off.
Switching to mainline kernel 4.9.6, or downgrading to BIOS 1.2.16
solved the problem. Other Linux distro users didn't observed the
problem, see also:
