Weird, on my Beagle xM C, 3.6.1 is fine...

omap2plus_defconfig + those ehci options listed above:
http://paste.debian.net/198630/

It does eventually crash:
[  7.261474] Kernel panic - not syncing: Attempted to kill init!
exitcode=0x00000b00

But it's more due to the other missing modules that
omap2plus_defconfig doesn't provide..
