it appears i have one bisection left to make but, just a bit of
info, the black screen issue kicks in when the kernel tries to change
the font size of the early kernel messages to a much smaller font (or
at least it happens around that time).
typically, regardless of the kernel, i get a couple of large font
messages (/dev/pts and one other, memory fails me), at which point a
good kernel will switch to a much smaller font and continue. with a
"bad" kernel, the display on my laptop goes black and stays that way,
despite the fact that the boot is obviously still progressing.
you can decide if that is at all helpful. back to bisecting.
should be getting close.
