It looks like the trouble starts after doing a scan for APs. The device seems to get set into an idle mode that's normally used when not associated to an AP, but then it's also trying to communicate with the AP. I can't see why this is happening though.
I've made a test build that enables dumping of verbose wireless debug information into the trace-cmd output. This is based on raring to also satisfy the upstream testing requirement, as raring is currently based off of 3.7-rc5. The link to the test build is below. After you've installed the test kernel you'll need to do a slightly different invocation of trace-cmd, but first it would be a good idea to bump up the size of the kernel's trace buffer. These commands will get you going: echo 32768 > sudo tee /sys/kernel/debug/tracing/buffer_size_kb sudo trace-cmd record -e mac80211 -e mac80211_msg Note that this is probably going to cause the trace.dat file to grow much quicker, so you might want to occasionally kill and restart trace- cmd to keep it from getting too large. Once you've got a trace of the disconnect, please give me the trace.dat file so I can have a look. This time could you also supply /var/log/syslog instead of dmesg so I can have the wpa_supplicant output in addition to the kernel log?
