So, I'm getting spammed hardcorely by my kernel (note that this is the log for only 1 second):

This repeats endlessly ever since I boot into my Gentoo Linux computer. And usb 1-4 is the only device which produces it (this would be my wifi-dongle, a carl9170-based TP-Link TL-WN821N device). To be honest, I have no idea on what could be producing the errors: I've always had problems with getting it to work previously in Gentoo, Ubuntu, Arch, and Debian, but I never had this kind of thing going on.
Also, I have this feeling that this may be related to the device suddenly turning unresponsive (or at least starting to drop my packets all of sudden, while still being connected to the router).
Any help will be appreciated,
Julian.
found the same thinh, Gentoo, 3.3.1. By the way it seems to occur at the same time the integrated WLAN card is going nuts after pm-suspend. – kagali-san – 2012-04-09T11:13:53.953
