    11.04 crashes after a while when bluetooth connectivity turned on

    Hey all,
    recently I've got this weird issue, and my laptop crashes when using my wifi or bluetooth to connect to the net.

    I alway see that syslog message:

    Code:
    Jul 24 06:49:47 r5k kernel: [  142.832042] scsi 4:0:1:0: abort 0
    Jul 24 06:49:47 r5k kernel: [  142.832052] scsi 4:0:1:0: Device offlined - not ready after error recovery
    and here's some more log:
    Code:

    Originally I had 10.10 installed, and this started happening some time after upgrading to 11.04.

    what can I do about that?
    thanx
