New Note 58
Given i.MX6 hardware with ARMv7 processor, I'm having intermittent failures
when connecting to access points.
It's intermittent in that I can sometimes connect to an access point then other
times, connecting fails. From what I can see, we authenticate properly, but
then fail to get a password via dhcp.
I'm running connman 1.25 and I'm connecting by using the DBUS interface. This
is built with Yocto.
Is there any other information you need?
Has this been fixed in a later release?
Is there a bugzilla I can go to in order to search for similar problems?
Here's the debug output from a failure.
