Subject2.6.13: Crash in Yenta initialization
Date
This does not happen in my current kernel (2.6.12-rc6 with Ivan's PCI bridge 
patches applied). It is definitely localized in the Yenta code, since the
boot proceeds when I disable the Yenta config option. My hardware is an Acer
Travelmate 8104 with the external ezDock attached.

I can provide more info if you let me know what to look for.
