How to partially fix the com.apple.driver.AirPort.Atheros crash December 3, 2007
Posted by Timothy Li in Airport, Leopard, atheros, crash.trackback
I’ve had a few unfortunate experiences with the kernel panic caused by “com.apple.driver.AirPort.Atheros” since I installed Leopard a few weeks ago.
To partially dodge this problem, I recommend you to disable IPv6 from your Airport System Preference and disable the auto-update option in the Mail application.
To disable Ipv6:
- Goto the System Preferences
- Click on the Network button
- In the Airport screen, click on the Advanced button
- Select the TCP/IP tab
- For the Configure IPv6 drop down menu, select the Off option
- Select OK and Apply on the way out
To disable the auto-update option in Mail:
- Select the Mail application
- Goto menu item Mail -> Preferences
- For the Check for New Email option, select the option Manually.
Hope this helps.

Nope, it doesn’t fix the problem (at least for me)
Hi Nikos,
Updated, hope this one helps you to sort it out.
Tim.
Wonder how you came up with the “turn of IPv6″ solution, but I am hoping it will work! :)
Hi till,
the ‘turn off IPv6′ solution actually comes from the link I provided in the post. Together with uninstall Azureus and disabling auto-update from Mail, the crash has not occurred for me for over a month.
hope that helps,
Tim.
no positive effect for me, crashes, spontaneous unsolicited reboots, and assorted kernel panics continue with gusto. all of this after a nuke and pave this past weekend. leopard positively blows.
