MacBook Pro Special Report: Kernel panics caused by AirPort drivers
Several readers have reported repeated kernel panics from their MacBook Pros, apparently caused by a problematic driver for the units' AirPort hardware.
This cause has been determined through the examination of crash logs generated post-kernel panic which identify the following components:
- com.apple.driver.AirPortAtheros5424(100.21)
- com.apple.iokit.IONetworkingFamily(1.5.0)
- com.apple.iokit.IOPCIFamily(1.9)
- com.apple.iokit.IO80211Family(110.19)
All of these components are required for usage of built-in AirPort hardware.
Also, the kernel panics only occur when AirPort is turned on and the network is active. Users report that kernel panics disappear when an Ethernet cable or other network connection method is used.
In some cases, these kernel panics can be attributed to problematic settings on the wireless router to which the MacBook Pro in question is connecting. Most users report that the problem only occurs on certain wireless networks -- usually with routers manufactured by third parties.
