We're having some issues here where toggling the last gpio pin (gpio 15) on a PCF8575 device causes platform to hang and I can't come up with any explanation of why would it hang... Any hints ? cheers --=20 balbi --27KoNqt0fmcl1zj/ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJSOKh0AAoJEIaOsuA1yqREFPQP+gKwfBNTzmxv3avpe6HwkPdP WE2RIXnJ+S4iaM8yeCD5Y9AyfaPn9VUlq+WiHPgeGB2xbs4N2hKo3BjRemWqh8qr HKBPeyQ7sg2zfawAkDsnp4hgIiAR6p5s34TtGN9kcWQ2TEuUnooDu6BQl+V81QIs m047GVXPOAOShBk8sbDT2TZfMEtoB+6uzcRVKZPupX0VGerYb6xcTzCuPEcNk2vn YZCG0Fh9S8SbtiOio3nx7V92d0NCvrN0Xe0HGhXUT6bkImsXsiaIUaJfdd3frXYU GiEWKjefCyAYkrmml6btNTnnhukJhqNjWVUP5yUlAuXIYhCES5kLIm7auVo+E9yw btI+dIQRdH+f1pNh+s1tLrw1wXVUm9VZvb9D6vM2rlPvpruVH3BMydOOWQetiVvw LhhnNjFeX7UX6PhhAhhOAbZ8W4hAIoJcfQgowoOra/hRaXuH9dVphpGBVugZY12Z uuiUIRd7XuWcMoElvecUaWnU7+ckf8psuYFHkPmxNCdlq+1I4pt00aBqI9A/N+pv dc296mOTlpeC2IuwHVHn8+uNfEunFCPYo9Tm3IVVqqxWF5caw5nqJcTNCcBxPQNt QEnKc9s3C4oXqa89QXby0nR9RClTG+BF71tx/CXCU96w9yBVocMTeIBhy5JQiCZ/ TbSQIHJXefP13erBinOP =LRSi -----END PGP SIGNATURE----- --27KoNqt0fmcl1zj/-- -- 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/
