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


I no longer have the system in the original report, and cannot verify
whether the issue is resolved or not. I would appreciate it if someone
else CC'd on this report would chime in -- I don't want to see this
issue dropped on the floor if it's still an issue for others.

  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).
