I am having this issue on mine too for some time. It happens in ArchLinux, Debian SID too. Started somewhere around 3.10 kernels I guess. my card is 02:00.0 Network controller: Intel Corporation Centrino Wireless-N 2200 (rev c4) I am running rawhide kernel 3.13rc6. I have to admit we have a bad issue with Tx aggregation with these devices. Can you please try to add disable_11n=2 as a module parameter? Thanks. Hi, I try to add disable_11n=2 as a module parameter, 'cos I have the same problem. I say you in few days the outcome of the test It seems to be OK for me : $ cat /etc/modprobe.d/iwlwifi.conf options iwlwifi 11n_disable=2 *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs. Fedora 20 has now been rebased to 3.13.4-200.fc20. Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those. I updated to 3.13.4-200.fc20 and still have the same issue. I also still encounter the issue. But it's getting rarer it seems, it did not happen since more than one month I think, but it just did a few minutes ago. I am a bit puzzled... Thus I am not sure how I will see if 11n_disable=2 fix anything. For the record, I am on 3.13.4-200.fc20.x86_64 Actually, it appears that the bug was constantly hitting me during the past hour. So I was able to make some tests and I can confirm that 11n_disable=2 seems to solve the issue. Kernel just updated and the problem is still there. When I boot kernel 3.12.10-300.fc20.x68_64 the problem seems to go away. My wifi is Intel Corporation Wireless 7260 (rev 6b). Everything worked fine until the kernel updated past 3.12.10-300. This will be worked around in 3.14-rc6 I think. I sent the patch that disables TX AMPDU to stable.

output of dmesg, truncated to the relevant part
The bug is still not fixed in kernel 3.14.7-200.fc20.x86_64. I was just hit a few minutes ago.
The same problem on Thinkpad 440s with intel 7260 using 3.14.8 and latest linux firmware. Very annoying but a google search seems to indicate that this happened even under windows. It would be nice if this can be fixed somehow. Fixed in the kernel bugzilla. Fix will be pushed upstream soon. Removing Intel from this bug - please re-add Intel if you think we have more to do. |
