Description Patrick 2012-01-15 15:15:26 UTC

Trying to debug another issue (with a wireless driver), by chance I found this "possible circular locking dependency".

Maybe some dev might want to have a look at those.

Here is another, I guess mostly identical though, lockdep debug message: https://bugzilla.kernel.org/attachment.cgi?id=72088

This "bug" is not really affecting me in day to day work (yet?).

It surfaced due to enabling CONFIG_LOCKDEP to debug a wireless driver issue, here: https://bugzilla.kernel.org/show_bug.cgi?id=42576

Closing, if this is still affecting you on a newer kernel please reopen.
