Ok, well the patch only will affect AP mode -- it addresses a bug where multicast AP frames are queued but not always processed. I wonder if your workload is just filling up the queues and then the queues are awakened prematurely. There's a check in ath5k_tx_processq to only re-enable the queue when there are 40 tx buffers left, but there are a few other paths that re-enable the queues -- also accounting on txbuf_len could theoretically get broken. Maybe a printk in ath5k_tx_queue of sc->txbuf_len caN show how many buffers are typically available when entering? -- Bob Copeland %% www.bobcopeland.com _______________________________________________ ath5k-devel mailing list ath5k-devel@lists.ath5k.org https://lists.ath5k.org/mailman/listinfo/ath5k-devel
