Steven Noonan, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc1 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: bios-outdated-0701 needs-upstream-testing ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- 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/876231 Title: very frequent warnings in kernel log with BCM43224 Status in “linux” package in Ubuntu: Incomplete Bug description: My kernel log is being filled by this: WARNING: at /build/buildd/linux-3.0.0/net/mac80211/rx.c:2910 ieee80211_rx+0x9b/0x1b0 [mac80211]() [... stack trace, etc ] at a very very fast rate. Since the stack trace shows it is in ieee80211_rx and the rate is so high, I'm guessing this is happening with every interrupt for the device. Any ideas as to the cause/fix for this? It makes it difficult to gather meaningful data from the kernel log when it's being filled by those messages. And any amount of traffic causes /var/log/kern.log to grow at a rather fast rate. This is mostly an annoying issue, as there seem to be no other real symptoms. Speedtest.net tests show it's achieving the same bandwidth I'd get if I was connected via ethernet (although kern.log grew from 7.2MB to 7.6MB just by running a single test on there).
