vm_soft_fault when discovering bluetooth devices

[monni]

How to reproduce: Run bt_discovery before starting bluetooth_server Experienced behavior: No KDL Expected behavior: whine like a baby

Hi monni,

Are you sure this happens before running the bluetooth server? Its because only the server comunicates with the driver, so the syslog would not have sense.

You ran more than once the bluetooth server? Currently it is really in pre-alpha and does not make, clean many stuff. Closing the debug window is not closing the server for example.

thanks for the testing!

I think I tried starting bluetooth_server once but it closed itself after minute or two... then I tried bt_discovery but it didn't print anything... so I looked in syslog and found that piece of information. Afterwards I started bluetooth_server again and bt_discovery worked without soft_fault.

It was right after I booted the system so memory was pretty much clean of residues from previous tests...

crash happens inside bt_discovery

got stack trace that contains only

<_APP_>:DumpInfoFPQ29Bluetooth11LocalDevice + 0x01a2
