Unfortunately, I don't have more info, but it looks like 100% reproducible: 10-15 minutes of copying files from server to laptop via AP (my old'n'good Atheros 9220) and AP (-CURRENT, very last one) hangs up without any messages at console. This HW has watchdog, so if watchdogd is running, AP reboots after 5 seconds, if watcgdogd is stopped it hangs till power cycle. I could not reproduce it with massive wire-only traffic or with 802.11g client. -- // Black Lion AKA Lev Serebryakov
