Comment 1 John W. Linville 2012-03-19 15:25:43 UTC 
Are you getting a lot of these?  Or just this one?

I'm not sure how important this is, if we really need a warning.  OTOH, if it happens a lot then it is surely a problem.
Comment 2 Ramón Mayo 2012-03-20 08:51:02 UTC 
Only sometimes, so i dont know how to reproduce it. Pluging again the usb wireless card didnt trigger it again.

Comment 6 Ramón Mayo 2012-03-24 07:36:32 UTC 
This night I got 5 of this warnings with the 3.3.0-4.fc16.x86_64 kernel again.
Comment 7 Bjarke Istrup Pedersen 2012-03-25 11:32:15 UTC 
I'm having the exact same problem on Gentoo with a vanilla kernel, so it's not Redhat specific.

I found out, that v3.1 is good, and v3.2-rc1 is bad, so I bisected it, and got this bisect log:

Which results in this:

19b4a8d520a6e0176dd52aaa429261ad4fcaa545 is the first bad commit

That commit seems to be a merge commit, so I'm unable to spot what it is in that commit that breaks things badly: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=19b4a8d520a6e0176dd52aaa429261ad4fcaa545

Any ideas would be welcomed.
Comment 8 Bjarke Istrup Pedersen 2012-04-01 15:25:02 UTC 
Does disabling CONFIG_PREEMPT also fix it for you?

It fixes it on my system.
Comment 9 Dave Jones 2012-10-23 15:30:59 UTC 
# Mass update to all open bugs.

Kernel 3.6.2-1.fc16 has just been pushed to updates.
This update is a significant rebase from the previous version.

Please retest with this kernel, and let us know if your problem has been fixed.

In the event that you have upgraded to a newer release and the bug you reported
is still present, please change the version field to the newest release you have
encountered the issue with.  Before doing so, please ensure you are testing the
latest kernel update in that release and attach any new and relevant information
you may have gathered.

If you are not the original bug reporter and you still experience this bug,
please file a new report, as it is possible that you may be seeing a
different problem. 
(Please don't clone this bug, a fresh bug referencing this bug in the comment is sufficient).
Comment 10 Justin M. Forbes 2012-11-14 15:07:39 UTC 
With no response, we are closing this bug under the assumption that it is no longer an issue. If you still experience this bug, please feel free to reopen the bug report.
