Hi,
I have a custom dm3730 board, which is booting fines with 3.2.x kernel.
However it oopses very early in the boot process with 3.4.x kernel.
I have some trouble interpreting the oops so some help is welcome.
I think what makes this board quite different from other setup is the absence
of Power Management IC.
Here is a patch that tries to hide the problem, and was needed for 3.2 not
to oopse :

+ // omap3xxx_voltagedomains_init();
omap3xxx_powerdomains_init();
omap3xxx_clockdomains_init();
omap3xxx_hwmod_init();
I guess this is a possible culprit, but any help on booting without
PMIC is welcome.
Below is the boot log.
Thank you for your help
