I am using 3.2.0 kernel with patches from Laurent Pinchart linuxtv
repository than enables mt9v032 on gumstix board.
I can capture images and everything, but I have one small problem.
Sometimes during bootup, kernel modules for omap3isp,v4l2,media
framework and mt9v032 driver are loaded automatically and sometimes they
are not. The problem is, that when they are loaded automatically the
boot process hangs for about 30 seconds or more and the last messages are:
overo: setting xclk to 25000000 hz
overo: setting xclk to 0 hz
and after few seconds everything works fine.
I tried to blacklist modules in modules.conf and in kernel boot
arguments but still those modules are being loaded sometimes.
Is there any way that I can reliably blacklist those modules in Angstrom
and/or is there a way to fix this hangup issue (I think there is
something in omap3isp code that causes the hangup when setting camera
clock, but those are only my assumptions).
