I have found a workaround for USB mass storage and EHCI controller (note that it's easier that OHCI). When USB DMA start, the driver (uboot sources) read with 1us period a register with 1S timeout. If I change this period to 10mS (yes in mS) Mass Storage not freeze the system and I started Kronos from my USB stick :-) Sure now this drive is like a floppy...

Maybe it's the same problem with ethernet, the driver freeze inside interrupt with big files.
