At machine A I have:

Everything starts fine, I can get packets flowing.

Then, without warning, the connection stalls.

hcidump on A finishes off with:

(Aside: The timestamps in hcidump don't appear to be working right.)

After this, trying 'hcitool info' on each querying the other just results in 
"Connection timed out".

I can't work out which end is at fault.

Machine A is running an unpatched 2.4.30, machine B 2.4.28. (2.4.29 had USB 
issues with my DVD burner.) Both are running bluez-libs and bluez-utils 2.17, 
and bluz-hcidump 1.21.
