If you are running a rootfs with hardfp with a kernel without CONFIG_VFP, the system should not finish booting. Where does the system hang exactly? We were talking about a hang when running switchtest. How do you produce the hang on a system without CONFIG_XENOMAI, since obviously you can not run switchtest? - -- Gilles. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Icedove - http://www.enigmail.net/ iD8DBQFTsYyPGpcgE6m/fboRAuwoAJ9TEgar4bWWtMMJrSqrStuEI647awCfdYK+ XhjleCJ3pCwymjmI0l/33hk= =ADfr -----END PGP SIGNATURE-----
