The bug is actually in iwlwifi, look at the error path in iwl_pci_probe: 12947 mutex_lock(&priv->mutex); [...] 12969 /* fetch uCode file from disk, copy to bus-master buffers */ 12970 err = ipw_read_ucode(priv); 12971 if (err) { 12972 IPW_ERROR("Could not read microcode from disk: %d\n", err); 12973 goto out_remove_sysfs; 12974 } and note that in the error path it doesn't unlock nor destroy the mutex. (I'd have changed the summary but I can't)
Actually, the latest rawhide kernel has a fix for this issue -- please give that a try. Also, this bug is triggered by the lack of iwlwifi firmware installed on your box. So, after you update to the latest rawhide kernel and reboot to verify that this issue is fixed, then you will need to install the iwlwifi-firmware package and reload the iwlwifi module: yum install iwlwifi-firmware modprobe -r iwlwifi modprobe iwlwifi Hth!
