List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "ath10k" Errors-To: ath10k-bounces+kvalo=adurom.com@lists.infradead.org To: ath10k Just FYI, I have no idea if this problem is with my patches, my firwmare, or what. At any rate, it is unlikely to be reproducible on upstream firmware due to its limitations in numbers of VIFS supported. Here is the problem: Previous to today, I was using wpa_supplicant that had sharing of scan results mostly disabled. It would only associate a single station VIF at a time, and mostly things were working up to 36 stations (yeah, I managed to eke out another 4 stations :)). But today, I started fixing the scan result sharing to work like it used to work back when I mostly tested ath9k systems. Now, after 20-25 or so stations vifs are associated (and most of the first 20 would be associating concurrently as possible), I get the errors below and ath10k is effectively hung: ath10k: failed to flush transmit queue (skip 0 ar-state 1): 0 This is very repeatable. My kernel does not have the latest two series of patches that Michal posted that deal with reset issues, so maybe they hold the key. So, I'm going to dig into this, but thought I'd throw this out in case anyone else is seeing something similar.
