[Bug 876231] Re: very frequent warnings in kernel log with BCM43224


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:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

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:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

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

  very frequent warnings in kernel log with BCM43224

Status in “linux” package in Ubuntu:

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).
