Thanks. I assume mainline is doing this now.
I guess it has to be dying in timekeeping_init(). Have you tried
earlyprintk=vga or, better, earlyprintk=serial,ttyS0,9600?
wish you would have said that earlier, i looked in
kernel-parameters.txt and didn't find earlyprinkt when searching for
debug :-(
two traces follow, one with the stock 2.6.17-mm4 kernel and the other
with the bisect kernel.
