repeatedly timeout connecting to the AP when it does correctly connect I see
this spammed in dmesg over and over again.

Comment 1 John W. Linville 2007-10-31 13:37:36 UTC
These kernels have some wireless updates not yet in the -41 kernel you are 


Would you mind trying to reproduce the issue with those kernels?  Does it 

Comment 2 David Nielsen 2007-10-31 14:06:17 UTC
I could successfully reconnect to the wireless after several warm boots, however
after a cold boot I could not connect to the AP again without restarting Network
Manager a few times.

All in all this is a fantastic improvement so far, the success rate has gone up
dramatically and so far I have not seen the error message.

Comment 3 John W. Linville 2007-11-09 19:26:21 UTC
Please try these kernels:


Are they working satisfactorily for you?

Comment 4 David Nielsen 2007-11-10 02:48:14 UTC
I've been running that for a good 18 hours now, so far it's the best kernel for
my wifi. It will still occasionally go into a state where it will claim that the
 progress of connecting to and getting an IP from the AP times out, this happens
most commonly when using WPA.

Also this:
phy0 -> rt2x00pci_write_tx_data: Error - Arrived at non-free entry in the
non-full queue 2.

Popped back up in the logs. So we aren't perfect yet but it's far closer to
being usable now.

Comment 5 John W. Linville 2007-11-29 14:47:50 UTC
A patch that was reported to fix this problem has been included in 
kernel-  Could you test that kernel and confirm whether or not 
it fixes the problem for you?

Comment 6 Dawid Zamirski 2007-12-07 01:53:08 UTC

I'm getting similar error with kernel- and rt73usb (Linksys

phy0 -> rt2x00usb_write_tx_data: Error - Arrived at non-free entry in the
non-full queue 2

Also, I got a few of those in messages log:
Dec  6 19:23:41 nufin kernel: phy0 -> rt2x00usb_vendor_request: Error - Vendor
Request 0x07 failed for offset 0x3040 with error -19.

When I pull out the NIC and then plug it back in, the connection seems to be

Comment 7 Mats Ljunggren 2007-12-08 08:54:52 UTC
I'm running kernel- and have a wireless NIC which uses the
rt61pci device driver. I get a lot of "phy0 -> rt2x00pci_write_tx_data: Error -
Arrived at non-free entry in the non-full queue 2." entries in the messages log
file with a very high rate. I counted the number of new messages I got in 10
seconds, and they were roughly 100.

Comment 8 Milan Kerslager 2007-12-18 08:47:32 UTC
I have RaLink RT2561/RT61 802.11g PCI card. I'm loosing connection since
kernel- kernel. I tryed kernel- kernel with no luck.

*** Bug 426874 has been marked as a duplicate of this bug. ***

Comment 11 John W. Linville 2008-01-02 19:40:48 UTC
Please try a later .fc8 kernel, one that includes the patch Ivo cited in 
comment 9 above:


Does that correct the issue for you?

Comment 12 Dawid Zamirski 2008-01-04 02:52:07 UTC
It works for me since kernel- - I havn't tested the 99th build
from koji yet.

Comment 13 Bryan Christ 2008-01-04 21:02:33 UTC
I would be glad to retest this on my system, but I am currently blocked from
doing so by another rt2x00 issue (buzilla 411481).

Comment 14 Mats Ljunggren 2008-01-09 19:35:33 UTC
I have now run kernel- for two days. I see no huge number of 
messages any longer. However, I still have a problem I had before. The link 
speed starts at 54 Mbps, but suddenly drops and goes down to 1 Mbps and stays 
there even though the link quality is good. I should mention that I only have 
about 5 meters between my wlan router and client, so I expect to have quite 
high link speed.

Comment 15 Ivo van Doorn 2008-01-09 20:37:44 UTC
Sounds like bug #382781

try setting your configuration to a fixed rate.

Comment 16 John W. Linville 2008-01-09 20:46:17 UTC
...and report any further link speed problems there, please. :-)

I'm going to optimistically close this based on comment 14.  Please reopen if 
the problem can be recreated with -99.fc8 or later.
