This may be more of a kernel problem - not sure.  In any case, sometimes in
recent attempts to suspend to RAM the laptop gets stuck, showing messages like this:

unregister_netdevice: waiting for wlan0 to become free. Usage count = 1

This happens with kernel and with the -33 kernel.

Hello Adam,

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.


I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel? If you are, please could
you attach an lspci -vvxxx output as well as dmesg output to this bug.

If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.

This machine is running rawhide now.  Suspend not working as of today, but I'll
report that separately.

Comment 3 Christopher Brown 2007-09-21 19:32:26 EDT
Please could you post back the output from:

# lspci -vvxxx
# lsmod

You may wish to also try rmmod'ing the wireless module in question and see
whether your machine is able to suspend successfully then.
