3.13.0-0.rc8.git4.2 is a rather odd kernel to still be running. Does the 3.13 final kernel hit this, or the latest 3.14.0-0.rc1.gitX kernel? This 3.13 kernel was fetched from repo days ago and then I didn't do any update. These kernels are installed: [rpmaker@fab Desktop]$ rpm -qa |grep -e ^kernel-3 kernel-3.14.0-0.rc1.git2.2.fc21.i686 kernel-3.14.0-0.rc0.git9.1.fc21.i686 kernel-3.13.0-0.rc8.git0.1.fc21.i686 kernel-3.13.0-0.rc8.git4.2.fc21.i686 ------------------- kernel-3.13.0-0.rc8.git0.1.fc21.i686 and kernel-3.14.0-0.rc0.git9.1.fc21.i686 neither worked on my thinkpad. Not exaggeration, I really wanted to smash it. ------------------- Yesterday I updated the kernel to kernel-3.14.0-0.rc1.git2.2.fc21.i686, during the update the brat throwed this out. disabling TX AMPDU will help here. TX AMPDU is disabled by default in 3.14-rc6 I think. I've also gotten this crash (same line number), and a much more frequent one at: drivers/net/wireless/iwlwifi/iwl-trans.h:743 iwl_trans_pcie_wait_txq_empty+0x374/0x3e0 [iwlwifi]() I can paste ABRT info if that's useful. It seems to be sporadic: I go without crashes for weeks and then suddenly I get a spate of them, like every few hours for the past couple days. I'm running 3.13.9-100.fc19.x86_64 kernel which I think is the current FC19 kernel. 3.14 was released about a month ago but I haven't seen an auto-update about it. I also looked at the change log for 3.14 and I don't see the commit about TX AMPDU there. Is there a way to turn TX AMPDU off from user commands, and/or is anything else likely to help? After one of these warnings, the wifi driver shuts down and I get an ABRT. Is there a way to bring the wifi back up without rebooting the whole computer? I guess I can manually install a kernel upgrade if I have to. Thanks. Paul I've still had these crashes happen in a couple of 3.14 kernels, currently 3.14.8-100.fc19.x86_64 . Should be fixed by https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/iwlwifi-fixes.git/commit/?id=7496d1162b8062cc360838290ac6680c2a196f22 which will be upstreamed soon. |
