As most of you may know, i.MX6DL ldo setpoint slightly changed along with updated datasheet rev.4 Dec.2014.
/* kHz uV */
396000 1075000 --> 1150000
So we took care of it and everything looked OK until yesterday.
Today we found almost same freeze problem when issued following command.
$ ifconfig eth0 off
It seems this problem happen just after clock frequency fell into 396MHz too.
If not issue such command, problem have never been observed.
Have someone ever heard such issue?
What's the difference w/ifconfig and wo/ifconfig?
Can someone help me?
