[Bug 1541392] Re: AR3011 Bluetooth not starting after being stoped (but detected)

[Michael Paulson]

With a fresh install of 16.04 on HP 4430s laptop, I have this same issue. BT worked before I setup my wireless network, and then didn't. I also can confirm the workaround above of shutting down the laptop, removing power(battery as well), seems to correct the issue. Fixes tried:
1. uninstalled and reinstalled bluetooth
2. echo "options ath9k btcoex_enable=1" | sudo tee /etc/modprobe.d/ath9k.conf
3. installed mainline kernel 4.6.3-040603-generic via dpkg -i
4. tried workaround above--seemed to correct, but for how long?

Steps to reproduce:
1. put laptop into suspended mode
2. Bluetooth icon shows on status bar, but will not reconnect
3. rebooted--> BT still Broken
4. shutdown laptop and removed all power
5. BT corrected

Attached BT_Issue_corrected.txt which shows when issue is occrring and when working(working part on bottom:
1. While the issue was occurring created BT_Issue.txt--> hciconfig > BT_Issue.txt, lsmod >> BT_Issue.txt, lsusb, dmesg | grep -i blue, lspci
2. While the issue was corrected created BT_Issue_corrected.txt--> hciconfig > BT_Issue.txt, lsmod >> BT_Issue.txt, lsusb >> BT_Issue.txt, dmesg | grep -i blue >> BT_Issue.txt, lspci >> BT_Issue.txt

** Attachment added: "hciconfig > BT_Issue.txt, lsmod >> BT_Issue.txt, lsusb, dmesg | grep -i blue, lspci"
