I'm on a lenovo thinkpad w520, on ubuntu 12.04, 64bit 3.2.0-26.
When I resume from a suspend, my bluetooth is non-responsive. My BT keyboard and mouse are doa. Wifi will reconnect, but bluetooth will not.
When this problem is happening, if I click Bluetooth Settings from the BT icon in the systray, it will delay for about 15 seconds before opening the Bluetooth Settings menu. When I click to add a BT device, it will just hang.
The only way to fix this is to reboot, and normally when I try to reboot at this point, it will hang, and I will need to do a power-off reboot.
I've searched a bit, and haven't really been able to notice any modern issues filed on this.
Any help is greatly appreciated.
