And it did cause problems with 8GB before IIRC.

Nono, they're free. There's no active pages after an unload. Thus, they're fine.
Ok, so now I need to go and audit things in more depth.
Thanks!

Ok, can you:
* bring the interface down cleanly (ifconfig wlan0 down);
* unload the ath driver (kldunload if_ath and kldunload if_ath_pci)
* sysctl hw.busdma, and just add it to the list here?
I'd like to make sure that it's freeing all the bounce buffer pages.
Thanks,
