ACL tx timeout (was Re: Unable to connect panu to pan): msg#00133

Subject: ACL tx timeout (was Re: Unable to connect panu to pan)
Well, I spoke too soon. Now I get the dreaded "[kernel] hci_acl_tx_to: hci0
ACL tx timeout" error on the NAP pc, and from then on I can't connect again,
getting only the "link key request" entries on the NAP and the following on
the PANU:

Jun 21 13:02:44 [pand] bnep0 disconnected : Connection reset by peer
Jun 21 13:02:49 [pand] Inquiring
Jun 21 13:03:02 [pand] Searching for NAP on 00:10:DC:AF:E1:13

dba=13:E1:AF:DC:10:00)
Jun 21 13:03:42 [pand] Failed to connect to the SDP server. Connection timed

Any ideas, any new data needed?
