Is there any detailed debug log for this type of issue? The -B on the
command line hides most of debug and for number of the details, more
verbosity would be needed. In other words "-B" should be replaced with
"-d" to get some useful messages..

I tried to find something useful from the ArchLinux bug reports, but
they seemed to be just providing minimal information from wpa_supplicant
and point to other bugs that more or less all had been closed as
duplicates of eachother.. There was no wpa_supplicant debug log that I
could find or any clear indication that this would be a wpa_supplicant
issue rather than something with netctl (or whatever configures and
launches wpa_supplicant here).
