I have some stability at now. )) 
If I do not use wifi acpi key then I have Wi-Fi and BT after reboot or sleeping. If I began use it and reboot with BT off then after reboot I can not switch on BT(only WiFi on/off). Dometimes after using wifi key I can select BT & WiFi on, widgets on tray say me - those device is on, but BT do not work(can not connect to paired mouse, or WiFi is on but I can not see any ISSD near me and can not connect to one.
Adter this, in BIOS I have no BT device(!), Only WiFi. I think ACPI module send some information to hardware which switch off it and BIOS can not recognize BT HW...
Only poweroff and battery off saves me. After inserting battery I go to BIOS and can see BT device enabled.

Title:
  168c:0032 [TravelMate B113-E] Has issues with bluetooth

Status in linux package in Ubuntu:
  Expired

Bug description:
  I have Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032]
  (rev 01) on Acer TM B113-E notebook.

  When I use ath9k with 3.11 kernel then all works fine. WiFi and Bluetooth works as well.
  I have problem with bluetooth when install some later kernels(I'm test 3.15rc1 and (3.13 or 3.14)) from http://kernel.ubuntu.com/~kernel-ppa/mainline/
  After this installation I have not bluetooth device! When I switch Wi-Fi by acpi key, I can switch only Wi-Fi to on or off state(I saw status by "rfkill list"). Bluetooth device will not reconize for me...
  But if I will power off  notebook and disconnect battery, then after power on I'm get working Bluetooth.

  I could not pay attention to this troubles but now we have Ubuntu 14.04(I tested on Kubuntu 14.04).
  After installed Kubuntu 14.04 I have working only Wi-Fi. Power off+disconnect battery and other probes(such as I probe to install non-free firmware) do not have results. System do not recognize BT device... I can not see this device in rfkill list and in KDE's System Settings->Bluetooth...
  In 3.11 kernel and later kernel I have problem with bluetooth after sleeping too. Module do not start after resume. I wrote script with manual starting of btusb module and get working BT after resume.

  My bluetooth device as per sudo cat /sys/kernel/debug/usb/devices :
