just in case you did not notice yet: U-Boot v2009.11-rc1 was released last night.
Hi,
I just tested it on my Dbox2 board where U-Boot 2009.08 is working perfectly well with unchanged config. But now U-Boot raises an exception during machine check:

The remaining boot messages would be:
In: serial Out: serial Err: serial Net: SCC ETHERNET LCD: ready
Any pointers where I could start debugging?
