So I decided to help out a bit and break this patch into several patches (to help tab integrate it). After breaking this patch into small pieces, it sounds like I forgot part of it ... and that was probably the cause of the bugs I was experiencing here ... So basically, I was chasing those bugs. I will have a look at the patches modified by Matt, and check if I get in the same problems. Still there seems to have a problem with syscalls as well, so the next step is to fix that too ... I'll let you informed of how it is going ...
