I somehow narrowed the problem down to x86_64. As soon as I use qemu-i386 on i386 or ppc the memory mapping tables are OK. When using x86_64 as host they are broken. Could this be a generic 64-bit host problem? I doubt that this actually has to do too much with the threading itself, because it works fine on other platforms. Alex
