[bluetooth-dev] stack seems to stuck



Hi,

I encountered a problem while doing some compatibility tests with openBT from CVS:

With my Anycom CF card everything works fine. I set up a RFCOMM connection
from a laptop to my embedded PowerPC system very recent Ericsson modules. Disconnecting is also fine.
(The Anycom card cannot handle Role switches.)

When I do the same with my IBM PCMCIA card, connecting is ok. After disconnecting the stack seems to stuck.
The last message in the syslog is hci_read_buffer_size - no response.

I attached the logs for the two disconnecting procedures.

Does anybody have an idea what happened here ?
