After ~ 23 hours: irq16: ath0 12086600069 146845 After 23h+5 minutes: irq16: ath0 12154198114 147131 About 10 minutes later: irq16: ath0 12307854569 147771 Now: irq16: ath0 14089141951 154492 And so on up to about 280000/sec. AP mode stops functioning at some point. It's a pretty old problem. However on older revs irq goes high immediately after boot, even if ath is not configured at all. HEAD rev 253412 Thank you! --help
