Recently, after performing a routine software upgrade, I notice a huge surge in the number of warnings from the kernel that goes like this:warning   kern [10839.717480] phy0 -> rt2800usb_txdone: Warning - Got TX  status for an empty queue 0, dropping warning kern [10839.895305]  phy0 -> rt2800usb_entry_txstatus_timeout: Warning - TX status timeout  for entry 11 in queue 2 warning   kern [10839.895325] phy0 ->  rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for  entry 11 in queue 2 warning   kern [10839.895327] phy0 ->  rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for  entry 11 in queue 2I think it has something to do with either the newly installed kernel-3.9.4-200 or wpa_supplicant-1.1-1 as the warnings appeared soon after these were installed. From the message itself, I think it has something to do with the wireless transmission, but not sure whether this is something serious as it is filling up my log quite rapidly.I am using a TP-Link wireless USB adapter. Has anyone encountered such problem or know whether it is something that I need to worry about?
What is TX status timeout and do I have to worry about it?

This looks to be an active bug in the rt2800usb driver. There's an open issue in the Fedora's bugzilla database here, titled: Bug 913631 - Slow wireless connection using rt2800usb driver (Asus USB-N13 dongle).TX status timeoutThe term TX refers to transfer (i.e. sending) and RX refers to receiver (i.e. receiving). I would say that it is something that you need to worry about given these messages mean your wireless driver & hardware combination aren't working 100% correctly. So you'll likely see either slow network access and/or flaky network connectivity.
