With the i2c devices removed, I get TTFF of around 1 minute in shr-core. It sounds like putting ferrite beads on SDA and SCL might help reduce EMI, so I will try that when I get a chance.

QTMoko v35 and I put this in /etc/default/gpsd:- START_DAEMON="true" GPSD_OPTIONS="" DEVICES="/dev/ttySAC1" USBAUTO="false" GPSD_SOCKET="/var/run/gpsd.sock" Before doing this it was pretty poor - worse than earlier versions of qtmoko and much worse than every SHR I've tried. On a reasonably clear day I now reliably get a fix in under a minute, sometimes within a few seconds. The only other varying factor (doubtful relevence) is that I got pissed with QTMoko and to a lesser extent SHR foobarring the SD card, so I'm now running from the card instead of NAND and everything is pretty good
