Kernel .config file used to compile the kernel in question
Greetings,
I'm currently experiencing hang up at boot time when using a Linux Kernel
4.10.0-rc2 on a Rockchip 3288 ARM board. Since I cannot login to the system in
such conditions, I'm using a UART←→USB cable and minicom to read the console
messages.
The system first hangs at:
[ 4.445965] ttyS2 - failed to request DMA
Then print the following after a few minutes:
[ 246.829223] INFO: task swapper/0:1 blocked for more than 120 seconds.

[ 248.164184] ---[ end Kernel panic - not syncing: hung_task: blocked tasks
Since the first backtrace relates to ext4 mount functions, I'm putting this
bugreport here.
However, I'm not sure where this bug comes from.
The system is a Rockchip 3288 MiQi board. The DTB is compiled from the
arch/arm/boot/dts/rk3288-miqi.dts file.
I'm attaching the kernel .config file used to compile this kernel.
The 4.9 kernels worked flawlessly, on that regard.
