Thank you for the bug report, please try booting with "btusb.enable_autosuspend=0" added to the kernel commandline and let us know if that helps. If this helps we're going to need a quirk for your laptop to automatically do the right thing, to add this quirk we need to know the DMI strings for your laptop, please run the following command: cd /sys/class/dmi/id/; for i in sys_vendor product_name product_version board_vendor board_name board_vendor bios_*; do echo "$i: $(cat $i)"; done And copy and paste the output here.
Thank you for the assistance. I've booted with "btusb.enable_autosuspend=0" added to the kernel line, and I see no results. I can confirm that this issue also persists for the kernel-4.16.6-302.fc28 If it's of help here are the DMI strings for my laptop, sys_vendor: Dell Inc. product_name: Inspiron 5565 product_version: 1.0.5 board_vendor: Dell Inc. board_name: 0RVKF9 board_vendor: Dell Inc. bios_date: 10/18/2016 bios_vendor: Dell Inc. bios_version: 1.0.5
Hmm, with a Dell with QCA rome bluetooth I would really expect that commandline option to help. Can you double check the kernel command line changes are being applied? After booting do: cat /sys/module/btusb/parameters/enable_autosuspend This should result in "N" (for no) being printed.
My bad, I forgot to run grub2-mkconfig. Everything seems to be working as expected now. I've tried the Bluetooth by booting several times today. Most times it works fine, sometimes though it doesn't recognize the Bluetooth as before. I noticed that when this happens the system prints something along the lines of "USB error 71". Are these related? In short, though, everything's working as should. I asked the above just for my curiosity. Thank you enormously!!
(In reply to Rodrigo from comment #4) > My bad, I forgot to run grub2-mkconfig. Everything seems to be working as > expected now. Great, so the next step is for me to write a kernel patch to automatically set btusb.enable_autosuspend=0 for Dell Inspiron 5565 laptops. I've the feeling that I might soon stop doing this on a per model basis and switch to doing this for all Dell laptops with qca-rome bluetooth. Anyways I'm not sure when I will have time to write the patch for this, hopefully this week. Once I've a patch I will build a Fedora test-kernel with the patch added and ask you to test that (with the kernel cmdline option removed).
I've written a patch adding a quirk to the btusb driver to automatically do the right thing on the Inspiron 5565. I've started a test kernel-build with the patch added here: https://koji.fedoraproject.org/koji/taskinfo?taskID=26955981 Note this is still building atm (this takes a couple of hours), here are generic test instructions for testing test kernel builds from koji: https://fedorapeople.org/~jwrdegoede/kernel-test-instructions.txt Please give this kernel-build a test and let me know it fixes things (without needing anything on the kernel commandline) and then report the results here. Once I've confirmation that this fixes things I will submit the patch upstream for inclusion into the mainline kernel.
Ping? Please test the provided test kernel and let me know if it fixes things.
Just gave a try. It worked as it should. Bluetooth works without adding "btusb.enable_autosuspend=0" to the kernel line. Thanks!
