Yes, those are quite normal; retries fail every now and then due to interference etc. The messages are written at lowest log level (KERN_DEBUG) which is not normally written into syslog. You can either configure your syslog not to log these or remove the debug logging from Host AP driver. Latest CVS version can be compiled with following command to disable all PDEBUG messages in the driver:


This will remove TXEXC reporting and some other messages. If you want to get rid of just those TXEXC messages, remove PDEBUG lines from prism2_txexc() function in driver/modules/hostap_hw.c (or prism2.c if you are using older version).
