This is affecting me too, on a system that worked perfectly with some older Ubuntu release (I guess it was 12.04 LTS but not 100% sure about it, sorry).
I did not see it mentioned anywhere on this BR but afaik the kernel bug is this - maybe could be helpful to narrow down the search for the fix: https://bugzilla.kernel.org/show_bug.cgi?id=61621 I tested some kernels on my system with these results: - 3.13.0-30-generic (Trusty's stock kernel) is affected - 3.13.11-03131104 is affected (and so are a few other 3.13.x that I tested) - 3.14.1-031401 works (and so do all 3.14.x at least up to 3.14.9-031409) - 3.15.4-031504 works - 3.16.0-031600rc2 and rc4 both work ** Bug watch added: Linux Kernel Bug Tracker #61621 http://bugzilla.kernel.org/show_bug.cgi?id=61621 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1318837 Title: 1814:0201 ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 0 failed to flush Status in “linux” package in Ubuntu: Incomplete Bug description: In Trusty, happens continuously 100% of the time after boot/reboot, finally fails, followed by authentication failure.
