Hi,

I guess I'm approaching the same or at least a related problem. I don't
feel like getting close the root of the problem yet but maybe the
attached output helps marcel or someone else to see clearer.

I can't pretend that the reset in the attached log is not beeing sent from a
user-application but i felt like the oops is worth posting.

Kernel used is 2.6.8.1 but i know that the thing happens also with 2.6.17.6.

Hardware used:

hci1:   Type: USB
        BD Address: 00:02:5B:00:BF:66 ACL MTU: 384:8 SCO MTU: 64:8
        HCI 19.2
        Chip version: BlueCore4-ROM
        Max key size: 128 bit
        SCO mapping:  HCI
        BD Address: 00:02:5B:00:BF:66 ACL MTU: 384:8 SCO MTU: 64:8
        Features: 0xff 0xff 0x8f 0xfe 0x9b 0xf9 0x00 0x80
                <3-slot packets> <5-slot packets> <encryption> <slot offset> 
                <timing accuracy> <role switch> <hold mode> <sniff mode> 
                <park state> <RSSI> <channel quality> <SCO link> <HV2 packets> 
                <HV3 packets> <u-law log> <A-law log> <CVSD> <paging scheme> 
                <power control> <transparent SCO> <broadcast encrypt>

                <interlaced iscan> <interlaced pscan> <inquiry with RSSI> 
                <extended SCO> <EV4 packets> <EV5 packets> <AFH cap. slave> 
                <AFH class. slave> <3-slot EDR ACL> <5-slot EDR ACL> 
                <AFH cap. master> <AFH class. master> <EDR eSCO 2 Mbps> 
                <EDR eSCO 3 Mbps> <3-slot EDR eSCO> <extended features> 

I don't expect any feedback on this, I'll post in this thread if I find anything..

Greetings

Andy
