Looks to me like it boots fine.  If you had hwmod debugging enabled, your 
kernel should have crashed after

omap-hsuart.0: ttyO0 at MMIO 0x4806a000 (irq = 72) is a OMAP UART0
omap-hsuart.1: ttyO1 at MMIO 0x4806c000 (irq = 73) is a OMAP UART1
omap-hsuart.2: ttyO2 at MMIO 0x49020000 (irq = 74) is a OMAP UART2

... but it didn't crash there.  I'm not seeing any hwmod debug messages 
though, so you probably don't have DEBUG defined in omap_hwmod.c.

So, I suspect whatever problem you're seeing is unrelated to the problem 
that the patch was intended to solve.
