As suggested by Paul on IRC I gave
http://openocd.zylin.com/#/c/2721/1
a try.

With that change, OpenOCD "resyncs" after a reset with "reset_config 
srst_only", but neither "reset halt" nor "reset init" work. After a 
reset the target is left running, halt etc. then work as normal.

I've attached a -d3 log just in case, and another one with additional 
"adapter_nsrst_delay 500".

Regards,

Dominic
