Huh - problem solved. It's been a memory setup issue :-(

But I still wonder why the error is forced, i.e. happens more often, when using network on u-boot.

If it is a SDRAM (DDR/DDR2) configuration issue, it likely is the DMA happening from network activity that is aggravating your misconfiguration. See especially the state machine part of http://www.denx.de/wiki/view/DULG/SDRAM

Using DMA makes addresses and sequences and timings jump around that simple program execution (especially if you have cache(s) disabled) doesn't do.
