resume problems with bluetooth

[dperson]

Binary package hint: acpi

Since adding the Dell BT (lsusb: Bus 002 Device 010: ID 413c:8103 Dell Computer Corp. Wireless 350 Bluetooth) to my Inspiron 6000D laptop (running kubuntu 6.06.1 and later 6.10), most times (9 out of 10) my laptop would freeze with a suspend / resume cycle. Adding bluetooth to the services that need to be shutdown and restarted in acpi-support did not solve the problem. I had to add the following files into the /etc/acpi directory.

/etc/acpi/suspend.d/50-bluetooth-stop.sh:
    #!/bin/sh

    # Stop bluetooth if it's running
    if [ -e /var/run/sdp ]; then
        /etc/init.d/bluetooth stop
    fi

/etc/acpi/resume.d/40-bluetooth-start.sh:
    #!/bin/sh

    [ -f /etc/default/bluetooth ] && . /etc/default/bluetooth

    # Start bluetooth
    if [ -n "$BLUETOOTH_ENABLED" ]; then
        /etc/init.d/bluetooth start
    fi

They are very loosely modeled on the irda scripts for a similar purpose.

I don't have problems with my laptop (a Dell Inspiron 9400) freezing, but my Bluetooth often does not work upon resume. These scripts fix that problem.

I am seeing similar freezing issues with my Thinkpad T43 (Bus 003 Device 003: ID 0a5c:201e Broadcom Corp.) running Ubuntu 7.04 (kernel is 2.6.20-16-generic). On resume from both suspend-to-disk and suspend-to-RAM, the screen remains blank and the keyboard and touchpad do not respond. These issues do not happen if bluetooth is disabled prior to suspend.

I experience freezing when Bluetooth is on when suspending too.
I am using Feisty on Thinkpad R52 with built-in bluetooth adapter. (Strange, lspci doesn't list any bluetooth device so I cannot find information about the adapter.)

For now, it looks good for me in Hardy. I installed Hardy even before the final release and have yet to experience a sleep problem, although I use bluetooth most of the time.

Is this still an issue for you? What Ubuntu version do you use? Thank you for telling us!
