Did this issue just start happening after a recent kernel update? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.

[Kernel-packages] [Bug 1301558] Re: [ath9k_htc] 14.04 NetworkManager hangs after 'ath: phy0: Unable to remove station entry for...'
I have not been able to reproduce it after a bit of testing on the mainline kernel 3.14.0-031400-generic, but it seems to happen randomly so I'm not sure that means it is fixed. I will continue to test for a couple days and see if it pops up with the 3.14 kernel. I just got this desktop on Friday and 14.04 was the first system I installed on it, so it is difficult to say when the issue started. I checked the old /var/log/kern.log.1 and it seems it also happened on March 28 with the 3.13.0-19-generic kernel. Today it didn't start until after I installed linux-image-3.13.0-21-generic. -- 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/1301558 Title: [ath9k_htc] 14.04 NetworkManager hangs after 'ath: phy0: Unable to remove station entry for...'

[Kernel-packages] [Bug 1301558] Re: [ath9k_htc] 14.04 NetworkManager hangs after 'ath: phy0: Unable to remove station entry for...'
** Description changed: This problem has been happening randomly since I installed 14.04. Today it happened twice while trying to zsync the latest iso. I use a TP-Link TL-WN821N wireless adapter to connect to the internet, which uses the ath9k_htc module. NetworkManager occasionally locks up to the point where any commands I try to kill it or restart it hang as well, and my only way out is REISUB. Right before it happens I have noticed twice in my dmesg: [ 494.896048] ath: phy0: Unable to remove station entry for: f4:ec:38:ec:42:02 For reference that mac address is the default router I connect to daily. and then shortly after we get a kernel dump for NetworkManager: [ 720.752078] INFO: task NetworkManager:850 blocked for more than 120 seconds.
