carl9170 AP mode stops working in 3.0.x

carl9170 AP mode stops working in 3.0.x

[Vladimir Menshakov]

Good day!
I've been using TL-WN821Nv2 dongle as AP for a year or so. I'm using
linux x86_64 desktop + hostapd. After upgrading to linux
3.0/compat-wireless-3.0-1/2, my AP started freezing after a while
(Maybe several minutes or so).
What I've tried so far:
1) switching hostapd in b/g mode.
2) checked /sys/.../power/autosuspend and various power-saving
features. (Seems to be unsupported by my device anyway)
3) upgrading to firmware-1.9.4 + latest compat-wireless version.

Sometimes restarting hostapd helps, sometimes not. I don't see any
relevant error messages or something suspicious in logs. (Tried
raising hostapd logs to maximum verbosity)
The last good configuration was 2.6.39-r3 + compat-wireless-stable-39.1

How could I help you find/debug this problem? I saw other complaint on
the mail list and I guess it's similar issue.

[I haven't noticed any problems with carl9170 AP, so I need
to know what commit broke the driver [shouldn't be too many]]

What other complaint are you referring to? [got a link?]

I have the same issue.

hostapd log:
http://pastebin.com/raw.php?i=23uxgBre

For me it's like 15-30 minutes. After that I can't connect to that
network but I can see it.
Only hostapd restart helps.

I tried older hostapd and 1.9.4 fw and it's the same.

I'm using Arch Linux with 3.0.4 kernel.
