Hi Beniamino, (Cc: to the mailing list as it may be of interest to others)
thanks for the patch, I will definitely give it a try during my next gta02 session. Today, I verified that the latest mainline kind of still boots on gta02, at least to the point when the frame buffer is initialized and a couple of init tasks are running. Then the fat task crashes in futex_up(). This appears to be related to the problem you are experiencing, because your vfs crash seems to happen in futex_down(). I suspect that something non entirely armv4 managed to sneak into the code used by futex_down/up().
