I don't think this two reports are separate issues. In both cases it is
triggered by processing of broken RX packages. In one case, wrong rate,
in other case wrong length. Lets start with rate, since it seems to be
easier to reproduce.
Theoretically packets with brocken rate should be just filtered out by
ath9k_cmn_process_rate. Lets try this patch:
diff --git a/drivers/net/wireless/ath/ath9k/common.c
b/drivers/net/wireless/ath/
index c6dd7f1..f7c4db0 100644
--- a/drivers/net/wireless/ath/ath9k/common.c
+++ b/drivers/net/wireless/ath/ath9k/common.c
@@ -205,6 +205,7 @@ int ath9k_cmn_process_rate(struct ath_common *common,
}
}
+ printk("Warning! Unsuported rate.\n");
return -EINVAL;
}
EXPORT_SYMBOL(ath9k_cmn_process_rate);
