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.

Best regards, gvb
of course you're right. But I'd expect the kernel gianfar driver doing at least as much DMA as the u-boot driver ... ;-)
After all it's definitely been a memory issue without doubt and all boards are running very stable now.
Thanks, Andre
