Public bug reported:

I use my computer to create a wifi hotspot to my local wired network.
Whenever I do so I get short hangs that last for about a second every few 
minutes.
Looking into the syslog in /var/log/syslog I get the output at the end of this 
message.
I have tried my best to look for an answer to this bug, but the reported bugs 
on wpa_supplicant are
all for other ret codes.

Best,

Victor
