I've finally been able to reproduce the issue you reported (lockup 
during boot), and it's really odd. It appears to only occur if I
leave off a couple of clauses from the kernel command-line:

	video=mxcfb1:off video=mxcfb2:off

Without that, something in the kernel startup seems to create
another frame-buffer on /dev/fb2:

	--------/sys/class/graphics/fb0
	DISP3 BG - DI1
	U:1280x720p-60
	--------/sys/class/graphics/fb1
	DISP3 FG
	--------/sys/class/graphics/fb2
	name: DISP4 BG
	mode: D:1280x800p-60

FWIW, my other display problem stemmed from me running
a kernel that had the Vivante driver built as a module
instead of statically into the kernel.

Regards,


Eric
