We have to conclude that your interface has been shut down as we have
gotten no beacons or RX data packets received. Unfortunately, my
restricting the output to only your AP does not let me know if any data
are being received. I hate to do this, but the attached patch will dump
all packets again with no limit. Once you get a disconnect, then you can
stop the run before the log gets too full.
No worries - disk space is reasonably cheap these days ;)
dmesg output:

wpa_supplicant output:

I noticed that I got several re-authentication attempts in the dmesg
output without the corresponding rtl_watchdog_wq_callback() line being
emitted - this is again something I don't see with zd1211rw and iwlwifi.
Once these drivers are associated, they seem to stay in that state for
hours.
Whilst checking various parts of my kernel, I noticed for the first time
during testing that my current kernel configuration doesn't have SMP
enabled. This got me thinking that perhaps there are other build options
which could have an effect on the driver. Hence I also uploaded a copy
of my .config file to http://www.ilande.co.uk/tmp/rtl8192cu-config in
the hope that maybe this can help you recreate the issue locally?
ATB,
Mark.
