Hi all,
My kernel version is linux-4.9.158, it hangs when replace the old u-boot(1.1.4) with u-boot-master.
For linux-4.14.xx, When I enable CONFIG_MIPSR2_IRQ_VI options, it does hang any longer while still hang in linux-4.9.158.
Sometimes it hangs at "random: crng init done".
Any hints will be appreciated!!! Thanks

It is hard to answer your questions. Many parts play with each other. ASo far I have following
questions:
- why do you change boot loader?
- why do you use old kernels?
- why you do not use devicetree?
- what is your memory layout? Where is loaded u-boot and where should be loaded kernel. Is kernel
compressed? Where it will be extracted?
Here is boot log on my system:

Thanks for your reply, I see your SoC is AR9331 which supported by u-boot-master either, and your bootloader is
barebox-2019. Maybe you can build a u-boot-master image for your AR9331 machine and you will know what happen!!! :-)
My BSP is openwrt-18.06 https://github.com/openwrt/openwrt. qca953x SoC.

It is hard to answer your questions. Many parts play with each other. ASo far I have following
questions:
- why do you change boot loader?
- why do you use old kernels?
- why you do not use devicetree?
- what is your memory layout? Where is loaded u-boot and where should be loaded kernel. Is kernel
compressed? Where it will be extracted?

It is hard to answer your questions. Many parts play with each other. ASo far I have following
questions:
- why do you change boot loader?
- why do you use old kernels?
- why you do not use devicetree?
- what is your memory layout? Where is loaded u-boot and where should be loaded kernel. Is kernel
compressed? Where it will be extracted?
