Excellent ! I have one too, so I should be able to reproduce your
setup. Which firmware/version do you use ?

Thanks ! nothing overly suspicious there, but I guess the reconnect
is where it happens. Might be interesting to see if we always lose
connectivity for good if we briefly disconnect.

I'll try some experiments later.

I just kill everything that doesn't look essential. E.g., on my usual
test machine I have right now only init, udevd, portmap (should get
rid of that one as well), dropbear, sh, getty, and anything I've
started manually.

BTW, on this machine, I just cleaned out the rc directories, so I
don't really go on a killing spree on each reboot, but the principle
is the same.

Thanks !
