If you look more carefully the first problem is actually a bus error: [ 15.776190] Unhandled fault: external abort on non-linefetch (0x1028) at 0xf9e3e044 [ 15.825925] PC is at omap_hwmod_read+0x14/0x28 [ 15.830583] LR is at omap_rtc_wait_not_busy+0x1c/0x44 I have no idea how the kernel manages to continue after a bus error in a driver (inside local_irq_disable even), but I wouldn't be inclined to take any later errors seriously.
