Hmm, debug the debugger time ...
Boot with command line option "kdb=early". At the kdb prompt, type
set KDBDEBUG=0xffff
set LINES 2000
go
After boot has completed, try to enter kdb. Record the complete trace[*]
and mail it to the list.
[*] You will probably need a serial console to capture the kdb trace.
