I am using a combination of DirectFB-1.0.1 and fusion 3.2.5 on my 2.6.23
kernel. The first application that I run, I get:
(!) FUSION_CALL_RETURN --> Input/output error
(-) [ 645: -STACK- ]

/usr/local/lib/libfusion-1.0.so.0 [0xb7e83000]

#2 0xb7e67f5b in direct_thread_main () from
/usr/local/lib/libdirect-1.0.so.0 [0xb7e55000]

Can anyone help me understand what my problem is and how to solve it?
