I am running rev 991 on an iBook G4 (openfirmware id PowerBook6,5) and Airport Extreme. I can associate with the base station, but I obtain TX timeouts after the driver has transmitted approximately 410 packets, where 410 is 80% of the number of DMA slots (512).
Upon further investigation, it appears that the function handle_irq_transmit_status() is never called, and therefore the driver never frees DMA slots in bcm43xx_dma_handle_xmitstatus(). Therefore, the driver suspends when reaching suspend_mark in request_slot() and never recovers. This behavior seems consistent with the reports of ``occasional'' TX timeouts by other people on this mailing list. I do observe bcm43xx_interrupt_handler() being invoked, but the ``reason'' variable never has the BCM43xx_IRQ_XMIT_STATUS set. I would appreciate if other people could confirm whether handle_irq_transmit_status() is called on their system, so that I can try to further diagnose the problem.
