With ht40+ on 44 I get MCS index 7 with transmigrate 150 reported on my macbook, that according to the table in http://en.wikipedia.org/wiki/IEEE_802.11n-2009 means 40MHz channel, with netperf-wrapper I get an accumulate of ~100Mbits/s (which actually sounds too good to be true I would have expected 75 tops, but with the macbook hogging all tops, there seems to be less wasted airtime for direction changes). So at least with country code GE channel 44 is capable of operating in ht40+ mode.

So with my non-working IP6 on 3.10.28-1, I get:
root at nacktmulle:~# cat /sys/kernel/debug/mips/unaligned_instructions
root at nacktmulle:~# uptime
19:35:13 up 11 days, 22:46, load average: 0.09, 0.43, 1.06
so most of the traps seem fixed!

Do yu know what their plan is? Put out a stable version an maintain that or switch to a rolling release cycle?
Best Regards & many Thanks for doing all this
