Using the driver results in a flood of [ 78.598403] ath9k: AR_INTR_SYNC_LOCAL_TIMEOUT [ 78.599508] ath9k: AR_INTR_SYNC_LOCAL_TIMEOUT [ 78.600500] ath9k: AR_INTR_SYNC_LOCAL_TIMEOUT [ 78.600833] ath9k: AR_INTR_SYNC_LOCAL_TIMEOUT [ 78.600833] ath9k: AR_INTR_SYNC_LOCAL_TIMEOUT [ 78.600833] ath9k: AR_INTR_SYNC_LOCAL_TIMEOUT [ 78.601378] ath9k: AR_INTR_SYNC_LOCAL_TIMEOUT in dmesg, and throughput is extremely slow. Surprising that there are multiple messages in a single time tick. I also tried with the ath9k driver from wireless-testing, as of commit 3fbf09eb3916 and got the same result. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
