Sorry for my belated response, but this usually happens when you access an aic chipset too soon after a chip reset. Try putting a delay before whatever access is causing this to see if it make s difference. Common problems include after a chip reset, touching any register will cause the card to reset, etc. --=20 Doug Ledford GPG KeyID: CFBFF194 http://people.redhat.com/dledford Infiniband specific RPMs available at http://people.redhat.com/dledford/Infiniband --=-Z7ubKhyjYxFWzD1CqxBl Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) iD8DBQBFC3O4g6WylM+/8ZQRAkMoAJ9bMRVyQVN8CAIQbMeCe1wMX8MrXACgkUbl D67khWM951RMKhHG5JOmn7E= =lKOW -----END PGP SIGNATURE----- --=-Z7ubKhyjYxFWzD1CqxBl-- - 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/
