I think indeed its a DMA-hardware-ath9k related problem. ?The patch in 2.6.27.8 didnt work for me. I have filled a bugreport on bugzilla.kernel but because AP isnt supported untill 2.6.29 the report is closed. I will test today 2.6.29.rc2 and see if it has any progress. gr, Willem -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
