I was giving 3.7-rc4 a whirl when I discovered my wireless adapter [0] wasn't
working: the LED didn't light up. Went and ran 'ip link' and it just hung there.
Tried a few other things and discovered that sudo was broken too. With
strace I found that they were hanging in sendto().
If I then unplug the adapter, everything comes out of the hang.
Bisected and found that commit ceb26a6013b962b82f644189ea29d802490fc8fc is
to blame.
Attached is my .config,. The complete dmesg is attached, as well as
dmesg_disconnect which is what gets spat out on disconnect of the device.
strace is an strace of 'ip link'.
I feel like I haven't given enough information; anything else needed?

I can see this issue too. I am not entirely convinced that the commit in
question is valid. If a HW reset fails for some reason in start(), bailing
out seems the right thing to do instead of continuing to fiddle with the HW
and silently returning a success code to mac80211.
I was able to bring up the device with this patch.

Hello,
I am experiencing exactly the same problem. I will try to revert the
commit in question tomorrow and report the result.
Thanks,
