random: nonblocking pool is initialized

[hemwant]

I am having a T1022 processor based board, the uboot is booting from spi and nand flash is used to boot kernel, device tree and file system. When i am booting kernel from nand flash it sometimes got struck in kernel. This behavior is very frequent . Please look into the attached kernel log for reference.

Processor : T1022

Nand flash - Micron MT29F8G08ABBCAH4

Please try whether this problem can be reproduce when using ramdisk boot, please refer to the following procedure.

=> setenv bootargs "root=/dev/ram rw console=ttyS0,115200"

=> tftp 0x1000000 nxa22585/t1024/uImage

=> tftp 0x2000000 nxa22585/t1024/uImage-t1024rdb.dtb

=> tftp 0x5000000 nxa22585/t1024/fsl-image-minimal-t1040d4rdb.ext2.gz.u-boot

=> bootm 0x1000000 0x5000000 0x2000000

I uploaded fsl-image-minimal-t1040d4rdb.ext2.gz.u-boot in the following link.

If this problem cannot be reproduced with ramdisk boot, please check NAND FLASH IFC timing configuration in u-boot source include/configs/T102xRDB.h.

For IFC timing configuration configuration on the custom board, please refer to https://community.nxp.com/t5/Layerscape-Knowledge-Base/IFC-Controller-Configuration-on-QorIQ-Custom-...
