That message is printed in response to a firmware interrupt. It
indicates "an unsolicited Frame Structure cannot be generated... because
there is not enough Frame Structure buffer space available".

I suspect that the beacons/probe responses/scan results are either too
large/too frequent for the card to handle, or the firmware can't
decipher them.

Before enabling wpa_supplicant, can you try scan for your AP (as root):

iwlist ethX scan essid YYYYY

I'm interested in what it returns, and whether dmesg reports 'Ext scan
results too large' or something similar.
