journalctl -b -k

I have a 2018 Dell XPS 15 9575 2-in-1 laptop (the one with VEGA graphics). The bluetooth adapter reports as 0489:e0a2 Foxconn / Hon Hai (which is curious, because all other references to this adapter in kernel.org date back to 2011 or 2012).

The bluetooth adapter works well until it abruptly dies. Often times, the bluetooth adapter simply dies in the middle of use, but the laptop going to sleep seems to increase the frequency of these issues.

I've verified that the issue does not exist in kernel 4.14.94-1 (although this kernel has other compatibility issues with my laptop.

I've verified that using modprobe to remove and readd btusb does not bring the bluetooth device back, and neither does restarting the systemd service.


I'm using Manjaro Linux 18 (Gnome 3.30.2), Systemd 239.303, and bluez 5.50-6.
Comment 1 Jacob C 2019-02-05 02:39:34 UTC
Given that the issue is not happening in 4.14, I tried (unsuccessfully) adding this line to /etc/default/tlp and returning to 4.20.


# Exclude listed devices from USB autosuspend (separate with spaces).
# Use lsusb to get the ids.
# Note: input devices (usbhid) are excluded automatically
USB_BLACKLIST="0489:e0a2"


The issue immediately returned after returning to the 4.20 kernel.
Comment 2 Jacob C 2019-02-05 22:11:14 UTC
I've just confirmed that this issue also does not occur on kernel 4.18.16_rt9-1, but this kernel also has various stability issues with the laptop. This issue seems isolated to just the 4.19 and 4.20 kernels.
Comment 3 Jacob C 2019-02-05 22:37:36 UTC
Unfortunately, it looks like I spoke too soon. This issue does persist in the 4.18 kernel mentioned above. The only working kernel I've found is the 4.14 LTS release which has various compatibility issues with the XPS 9575.
Comment 4 Jacob C 2019-02-05 22:49:40 UTC
Not sure if it was related, but I see this in my journalctl -b -k

Comment 5 Jacob C 2019-02-22 00:07:06 UTC
This issue persists in kernel 4.20.10

I still haven't heard any feedback from anyone on this issue... is there something else I need to do?
Comment 6 Jacob C 2019-03-26 16:43:21 UTC
Sadly, this issue persists in the new 5.x kernels as well. :(
