On -next, Above crash signature could be related to race 
"ARM: OMAP2+: omap-device: fix race deferred probe of omap_hsmmc vs omap_device_late_init"
http://www.spinics.net/lists/linux-omap/msg121622.html

Especially if before crash smth. like below appears in log:
> [ 1.840364] omap_hsmmc 480b4000.mmc: omap_device_late_idle: enabled but no driver. Idling
> [ 1.840634] ldousb: disabling
