It looks like we are not getting a response to the HCI_Reset command. The
BT stack will send this command, wait 4 seconds for a response, send it
again if no response was received and repeat this 3 times total before
giving up. This is what happened in your case.

The Bluetooth stack is expecting a command complete packet to be received
for this HCI_Reset command. Could your driver be missing interrupts?
