== SRU Justification ==
The rt2x00 driver gets frequent occurrences of the following error
message when operating under load:
phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in
the non-full queue 2.
Wireless eventually fails and the driver must be reloaded in order to
operate.
For Oneiric, this is a clean cherry-pick from upstream commit 77a861c4.
Natty needed minor fix-ups to apply cleanly. Bug reporter has tested
and confirmed this resolves the issue.
== Impact ==
Bug reporter has Ralink corp. RT2800 802.11n PCI [1814:0601] card
== Test Case ==
Under load look for the message "phy0 -> rt2x00queue_write_tx_frame: Error - Arrived
at non-free entry in the non-full queue 2." and wifi eventually fails.
With a patched kernel, under load, message is not see and wifi continues
to function.
== Fix ==
Upstream commit 77a861c405da75d81e9e6e32c50eb7f9777777e8
-----
After a few hours of use, the natty version of rt2x00 wireless driver writes to syslog:
phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 2.
After this all wireless service stops, and the rt2x00 module has to be unloaded/reloaded to start again.
I have found a solution to this problem in the form of a patch here: http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2011-June/003932.html
After applying this patch, the problem is resolved. However, this patch fails on the current linux-source-2.6.38.tar.bz2 ubuntu source code. I have created a new patch which works perfectly, but I am forced to rebuild the module each time a new kernel is released. Is there any way we can have this patch added to the rt2x00 module that ships with Ubuntu permanently?
