9360 Bluetooth Issue
Hi, Running Ubuntu on XPS 13 9360, having an issue where bluetooth is no longer available after suspend, and appears to not be on/enabled. Works fine after restart, but after suspend I lose all bluetooth connections. I can turn it off, but not back on. Also installed blueman and doesn't appear to have helped with this issue. Anyone else run into this and have any suggestions?

I also have this issue, running Ubuntu 17.10
Linux voyager 4.13.0-21-generic #24-Ubuntu SMP Mon Dec 18 17:29:16 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Is there any known solution to this?

I have had this issue too, starting in November but seems OK at the moment (Fedora 27 14.4.8). I think the problem could be intermittent.

Hi,
I had a similar issue of Bluetooth disappearing some times after an unsuspend on Debian. After power on, it works, but if I suspend and unsuspend, Bluetooth disappears after a while.
I'm not sure it's exactly what you experience, but it looks exactly like the symptoms of th "Bluetooth Stopped Working" thread, but this one has unfortunately been locked, so I can't seem to answer there.
I also have the
message in syslog.
It doesn't look like a hardware issue, looks more like a driver/power management problem with the tlp package.
I found that I could workaround this by blacklisting btusb from autosuspend in /etc/default/tlp (on Debian):
It looks like tlp is autosuspending USB Bluetooth when it shouldn't. This avoids that issue. Only issue I have is that sometimes, bluetooth doesn't reappear on unsuspend. Hibernate and unsuspend again fixes it.
Hope this helps anyone with the issue.
