Its really not obvious to > me at all why that patch is breaking things though... My POWER5 (gr) LPAR seems to boot ok (3 times so far) with that patch, gues= s=20 it's something subtle. That's with CONFIG_DEBUG_MUTEXES=3Dy. And it's just= =20 booted once with CONFIG_DEBUG_MUTEXES=3Dn. And now it's booted the full mm4 patch set without blinking. cheers =2D-=20 Michael Ellerman IBM OzLabs email: michael:ellerman.id.au inmsg: mpe:jabber.org wwweb: http://michael.ellerman.id.au phone: +61 2 6212 1183 (tie line 70 21183) We do not inherit the earth from our ancestors, we borrow it from our children. - S.M.A.R.T Person --nextPart3187557.rjtkziG21e Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQBDzPH+dSjSd0sB4dIRApilAJ9yEZUN2DyWlAzQOujduK5GjvNWnwCgvcbC nkvKqN1MHVXOS8DeJaMmAgQ= =qy8v -----END PGP SIGNATURE----- --nextPart3187557.rjtkziG21e-- - 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/
