Hello,
I'd like to test out newer kernel on a Beagleboard B6 but latest
trees from Linus, linux-omap and linux-omap/for-next seem to be failing at
early boot [1] with omap3_beagle_defconfig.
Some bisecting shows that ARM_UNWIND broke something in the defconfig since
kernels before adf8b37bafc1495393201a2ae4235846371870d0 "[ARM] 5386/2:
unwind: Add Makefile and Kconfig entries for ARM stack unwinding" work.
If UNWIND is breaking it, then the most likely cause is that you are
using an older toolchain, such as code-sourcery 2007q3. If you are using
2007q3, upgrade to a 2008 or 2009 release. More details here:

On the other hand, setting ARM_UNWIND to n which falls back to FRAME_POINTERs
work until 84e250ffa76dddc1bad84e04248a27f442c25986 "musb: proper hookup to
transceiver drivers".
You could trying enabling "CONFIG_TWL4030_USB" to see if this helps.
