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 I just hit strange and wonderful crashes because I managed to use an msdu-desc length that was not an even multiple of 8. Firmware has assumption (bug, really) about this. Bug is only triggerable if you fill up tx-descs, so have to flood UDP to hit easily. I was trying 812 buffers, but 808 works just fine. (non CT firmware will not let you do less that 1024, no matter what you request, btw). Easy to fix though once you know the problem.
