Hello,
I was able to get kgdb working - I did not run 'make installworld' of
course and the old kgdb version couldn't get along with the 6.0 kernel
(I suppose). After installing the libraries needed by the new kgdb
binary by hand, I can give you some additional info:
Unread portion of the kernel message buffer:

Previous frame inner to this frame (corrupt stack?)
Hope this helps.
Unfortunatly I am unable to get the dump of the other panic (the one
which occured earlier in boot phase), since there is no dump device
defined at this point.
