let me know if and how I can help
meanwhile 4.10.12 and same symptoms.
seems 4.10.13 no longer suffers from 195329 Thanks for fixing.
4.11.0 fine as well
Oops : 4.11.0 does suffer from 195329 (and 4.10.13 was fine). May need to reboot few times to double check. Will reopen this defect if 195329 consistently present in 4.11.x ...
It seems if one powers down ('shutdown -h now' -not- 'shutdown -r now') then upun reboot, stick initializes itself properly. So I keep state resolved.
