John, Larry, this particular kernel still had compat-wireless-20120209 enabled. Any ideas what changed in this kernel? Driver rtl8187 has not changed for some time, and I have never seen this problem. I would not expect any problems with compat-wireless, but who knows? As this is a 3.3-rc3 kernel (probably from mainline), what happens when you do not enable any compat-wireless? Could such a test be done? For rtl8187, nothing would be missed. We take read_lock before ->led_brightness_set, I guess this bug was never triggered because _sync part of cancel_delayed_work_sync is very rarely used. I think changing to cancel_delayed_work() should be fine. Is this still happening with the shipping 3.3 kernels (compat-wireless was not in the 3.3 stable kernels) This bug is not fixed. I posted fix for this bug: http://marc.info/?l=linux-wireless&m=133715936315740&w=2 Thanks, applying kernel-3.3.6-3.fc16 has been submitted as an update for Fedora 16. https://admin.fedoraproject.org/updates/kernel-3.3.6-3.fc16 kernel-3.3.6-3.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/kernel-3.3.6-3.fc17 Package kernel-3.3.6-3.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days.
