Interesting. For me the latest nightlies are working quite well with WPA2 CCMP. I have changed nothing on my network. The WAP in question has an uptime of 216 days and I have made no config changes.

I'm still seeing what appears to be MMC oddities. MMC background operations will start and *never* end.

mmc0: mmc_start_bkops: raw_bkops_status=0x1, from_exception=0
mmc0: mmc_start_bkops: Starting bkops

When this starts it feels like filesystem performance is not very good. No numbers yet but seat-of-the-pants feels very slow, relatively speaking.

Upon reboot it appears that partitions are not cleanly unmounted --

I'll try running iozone next time this occurs to get some numbers. Would there be any other benchmark or utility recommended?
