2.6.29-based kernel, hitting this WARN in iwl-tx.c:
 
       /* If a Tx command is being handled and it isn't in the actual
         * command queue then there a command routing bug has been introduced
         * in the queue management code. */
        if (WARN(txq_id != IWL_CMD_QUEUE_NUM,
                 "wrong command queue %d, sequence 0x%X readp=%d writep=%d\n",

Comment 2 reinette chatre 2009-04-14 16:01:09 UTC 
Which hardware?

This is a ucode issue for which the latest 4965 ucode will fix it. We are working on getting ucode for 5100 out the door.
Comment 3 James 2009-04-14 16:05:39 UTC 
4965 hardware with iwl4965-firmware-228.57.2.21-4.noarch. I notice .23 is in Koji, but not for rawhide --- update available?
Comment 4 James 2009-04-14 16:10:54 UTC 
(Ignore my previous comment, the .23 package does install on Rawhide without complaint. Furthermore, I've not seen the backtrace so far with kernel-2.6.29.1-70.fc11.x86_64.)
Comment 5 John W. Linville 2009-04-14 17:09:04 UTC 
Updating rawhide version of iwl4965-firmware...
