Ok, then just try to get the working version, and find the difference.
From my mind, it should be PLL related.
Here I am again ;-)
The following log is taken by an automatic-script during bootup (rc.local).
the smtp_device.c throw a time out, so the imx_ehci logs an error during
bootup: unable to init phy
=EE= HW_CLKCTRL_PLL1CTRL0: /dev/mem opened.
Memory mapped at address 0xb6f30000.
Value at address 0x80040020 (0xb6f30020): 0x60000
=EE= HW_CLKCTRL_PLL1CTRL1: /dev/mem opened.

after issuing a soft reboot (invoking reboot command) here is the new log:
=WW= HW_CLKCTRL_PLL1CTRL0: /dev/mem opened.
Memory mapped at address 0xb6f5e000.
Value at address 0x80040020 (0xb6f5e020): 0x60000
=WW= HW_CLKCTRL_PLL1CTRL1: /dev/mem opened.
Memory mapped at address 0xb6fc9000.
Value at address 0x80040030 (0xb6fc9030): 0x800004B1
So the hardware CLKCTRL_PLL1CTRL[0/1] registers have the same value.
Any other clue?
