Bisection says: git-ipwireless_cs.patch GOOD # git-x86.patch git-x86-fixup.patch git-x86-arch-x86-math-emu-errorsc-fix-printk-warnings.patch git-x86-drivers-pnp-pnpbios-bioscallsc-build-fix.patch git-x86-fix-doubly-merged-patch.patch git-x86-export-leave_mm.patch BAD and that's where bisection comes to a halt... Time to bisect through git-x86, or somebody got a better idea? Looking at the commits listed in git-x86.patch, I didn't see anything that jumped out, but I'm pretty sure the problem is in there somewhere... --==_Exmh_1198944128_3550P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFHdm+AcC3lWbTT17ARAte4AKCRFNxVTYSbaD7CD+i97PQoq1XbxwCg4757 w7nomM/lywuLZLLJ8ljbnWs= =J44v -----END PGP SIGNATURE----- --==_Exmh_1198944128_3550P-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
