I think there is a problem with the linkcmds of the virtex BSP in 
4.7.99.2. The linker script defines _end to be at the end of the .data 
section whereas I think it should be defined to be at the end of .bss. 
Please correct me if I'm wrong.

Attached please find diff against a linkcmds I'm using for a Virtex II 
Pro board.

HTH.

Regards,
Jukka
