I can't get to a prompt, so I can't provide this, but it's 6.99.3 built from 
sources as of two days ago.
I'm encountering a panic when trying to boot a 6.99.3/macppc kernel
built from sources as of two days ago.  This is a generic kernel,
except with options DIAGNOSTIC and DEBUG enabled.  I did not have
this problem with 5.99.65.
