+Subject: [PATCH] ath9k: make DMA stop related messages debug-only
+
+A long time ago, ath9k had issues during reset where the DMA engine
+would stay active and could potentially corrupt memory.
+To debug those issues, the driver would print warnings whenever they
+occur.
+
+Nowadays, these issues are gone and the primary cause of these messages
+is if the MAC is stuck during reset or busy processing a long
+transmission. This is fairly harmless, yet these messages continue to
+worry users.
+
+To reduce the number of bogus bug reports, turn these messages into
+debug messages and count their occurence in the "reset" debugfs file.
