Re: [4.8.0-rc1] am335x-evm boot failure: n_tty_receive_buf_common: "Unable to handle kernel paging request.."

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.
