Message-ID: <4CA81265.8030403@candelatech.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ath9k-devel@lists.ath9k.org This on wireless-testing from Friday, plus a few debugfs patches I posted recently. I was running two STA just fine, and then tried to add 128 more. After that, nothing will authenticate (timed out). I don't see any obvious errors in the logs, other than DMA failing to stop after 10ms, but this debugfs information looks quite suspect: [root at atom lanforge]# cat /debug/ath9k/phy0/wiphy primary: phy0 (ACTIVE chan=0 ht=0) addr: ef:be:ad:de:ef:be addrmask: ef:be:ad:de:ef:be rfilt: 0xdeadbfef UCAST MCAST BCAST CONTROL PROM PROBEREQ PHYERR MYBEACON COMP_BAR PHYRADAR MCAST_BCAST_ALL It seems some sort of race..if I add and configure these interfaces manually, it seems to work. It may also be a problem with bringing up the interface before applying the wifi settings, as that was the last change I made to my user-space application that manages these interfaces. I briefly saw the deadbeef when configuring manually..but the single wlan0 seemed to be associated OK, and when I added another station, the values went back to normal. Any ideas what this might indicate? Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
