The system hangs in linux at bootup if the linux ethernet driver is started and no ethernet cable is connected.
Boot from NAND Flash with u-boot environment variable ip=DHCP or ip=192.168.xxx.xxx.
Problem occurs on the freescale eval board (Sabre SD) boards and on our own board.
The cpu seems to go idle mode. We use the standard kernel configuration
CPU: iMX6 Solo, latest BSP 4.1.0

Hi, her
You should not adding ip=DHCP or ip=192.168.xxx.xxx. in uboot command line if you do NOT have ethernet cable connected.
where does it hang? if your filesystem is being NFS mounted, then this is the expected behaviour. As Youngcai mentioned, try to avoid the 'ip' parameter of add 'ip=none'
