Title:
Missing wifi and bluetooth after sleep on XPS 9370
Status in Dell Sputnik:
New
Status in linux package in Ubuntu:
In Progress
Bug description:
I have XPS9370 with self-installed Ubuntu 18.10 (not project sputnik) with
Killer 1435 wireless module.
And sometimes I find wifi and bluetooth missing after sleep. I cannot exactly
define preconditions, but it seems there are following steps to reproduce the
issue
1. Connect something via bluetooth (I use bluetooth headset)
2. Send laptop to sleep
3. Wake it and find wifi and bluetooth missing.
I have to mention that I have also been experienced bluetooth only
missing, but it somehow transformed to the issue with both wireless
devices.
Dmesg after waking up with the issue attached
