I can ssh to my gta04 and restart qtmoko, after which, all is well. Is there any reason for this (not hanging up /dev/ttyHS3 or holding /dev/ttyHS3 open)?

1/ I strongly recommend you install

https://github.com/neilbrown/linux/blob/gta04/3.4.y/GTA04/udev-rules/hso.rules

in /etc/udev/rules.d

So that you get names like /dev/ttyHS_Application etc which are stable.
Sometimes the "ttyHSn" names move around.

2/ I use /dev/ttyHS_Application for the main control of the GSM module,
 /dev/ttyHS_Modem to make sure I get "NO CARRIER" messages,
 and /dev/ttyHS_Control for other things like setting up networking.

If yo use ttyHS_Control that should leave qtmoko unaffected.
