bluetooth stops working after suspend

[D Becker]

Bluetooth stops working after suspend to ram. Under Jaunty everything worked properly.

When working, lsmod | grep bt shows:
    btusb 14260 4

..and the bluetooth applet appears on the panel, etc. After resuming from suspend, with or without toggling the bluetooth adapter (via key combination, but apparently its built into the hardware), lsmod shows "used by" of 0 instead of 4, the bluetooth applet disappears, the device doesn't show up in lsusb anymore, and bluetooth-properties claims there are no bluetooth adapters present.

After reboot it works normally again, including enabling and disabling the adapter with the key combination.

Switching to a text console before pressing the key combination makes no difference, nor does removing/reinserting btusb, or restarting /etc/init.d/bluetooth (all of which have been tried both before and after the key combination).

I'm not sure which package has the problem, so I've listed the versions of several that seem potentially relevant below.

Software versions:
Ubuntu 9.10 upgraded from 9.04, amd64
bluez: 4.51-0ubuntu2
hal: 0.5.13-1ubuntu8
udev: 147~-6
kernel: 2.6.31-14-generic

Hardware:
system: Clevo M570TU laptop (a recent System76 Bonobo Professional)
BT device from lsusb:
    Bus 008 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

Hello,

Does the problem still appears.
When it appears, could you run the following commands and post the result here?
- hciconfig
- rfkill list

Does restarting bluetooth daemon solves the issue (sudo invoke-rc.d bluetooth restart)

thanks
