panic error with powerpc/virtex BSP

[Pierre Kestener]

Thanks to all for your answers.

The problem still remained after applying the patch. But then I noticed 
that the "hello world" application that I was using was from the archive 
release example-4.7.99.2.tar.bz2
where the Makefile defines

MANAGERS=io

After adding semaphore to the manager list (as it is done in the 
testsuite hello_world), it worked !
