Hello Knurpht:

Thanks for the kind suggestion, I did update the /etc/default/tlp setting as
you suggested, but I don't think tlp is enabled on my system:

$sudo tlp-stat -s

$ bluetooth

Your hint sounded plausible initially, but now I'm skeptical that tlp was
the culprit.

With best regards:

Bill

Hello Oliver:

Thanks for your advice, we are now tracking this now on
https://bugzilla.opensuse.org/show_bug.cgi?id=1070434.

Regarding bisecting the kernel, have been running Linux on this machine
with unstable bluetooth since October 21, 2017, the machine's specs per
the
vendor are https://support.hp.com/us-en/document/c05787871. Is bisection

supposed to isolate the transition from broken to fixed (or vice versa if
we have a regression). If all states are broken, how will I bisect? The
hardware is pretty new hence the need for a new kernel (4.6+ according to
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi ofr intel 8265

iwlwifi is the wireless driver for Intel's current wireless chips. For older
chips, there are other drivers:

I dual boot into windows and the bluetooth seems reliable under windows,
so
I am ruling out hardware issues. On a side note, I put Bumblebee on this
system last night (tainting my kernel) to address screen flicker, but the
bluetooth issue predates that.

Your XHCI is failing catastrophically. The failure of Bluetooth is
among the expected consequences. The best way to debug this is to
bisect the kernel. Could you do that?
And please make a bugzilla entry for such issues.

Regards
Oliver

What I needed to get bluetooth back working on TW on my HP laptop:
Setting BLACKLIST_BTUSB to 1 in /etc/default/tlp
Using rfkill to unblock the BT device.
AFAIK tlp gets started by something else.

What does
rfkill list
say ?
