Maybe this is better?=20 CONFIG_IDE_TASKFILE_IO This option enables a new standardized data-transport driver. It replaces code currently in each chipset/host driver. This should help reduce bugs and allow better data protection. This new code also packetizes requests to enable rapid performance and reduce system latency. It also u= ses structures so MMIO hardware can be used in second generation Ultra133 and Serial ATA chipsets. Since this a a major reworking of current code, this will live along side current drivers for now. If this doesn't work on your arch yell.=20 If you want to test this new driver (and have backups), say Y here.=20 >=20 > TIA > Adrian >=20 >=20 > - > 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/ --1yeeQ81UyVL57Vl7 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8slUYUHPW3p9PurIRAopjAKCpQHJr+PBDRP0ZO+WRp7Cw78iCwACggNJa wo4ibVnXRtgBPfm5hFRuiZo= =A1qJ -----END PGP SIGNATURE----- --1yeeQ81UyVL57Vl7-- - 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/
