Synopsis: [msk] [panic] if_msk driver causes kernel panic (fatal trap while in kernel mode) State-Changed-From-To: open->feedback State-Changed-By: yongari State-Changed-When: Thu Feb 10 18:41:33 UTC 2011 State-Changed-Why: It seems there are two issues here. o Station address read by driver was ff:ff:ff:ff:ff:ff o PHY attach failure triggered panic I have no idea for the first issue. It seems you have 88E8056 Yukon Ultra controller which is known to have several stability issues with msk(4). Due to lack of hardware I was not able to track down the root cause of the issues. However I can't reproduce the panic on my box when I patched the driver to fail attaching a PHY. By chance are you using VIMAGE enabled kernel? If yes, how about removing VIMAGE in your configuration and test again?
