Machine: macppc
> Description:
A current kernel for macppc built with DEBUG and DIAGNOSTIC crashes
during boot. The stack trace does not seem to point to a problem
specific to macppc, hence why I'm filing this in the kern category
directly. The problem seems to be caused by the ohci driver.
The stack trace is (manually copied; might contain typos):
[...]
