I.e., how did you determine the existence of this bug? And please cc: the sata_promise maintainer on sata_promise patches. (Hint: that's me) And please choose a Subject: that makes it absolutely clear what the post is about. "Sata Sil3512 bug" doesn't exactly sound like something the sata_promise maintainer needs to look at. Meanwhile I'll check the Promise driver(s) to see if there's something about SG table formatting restrictions there. /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
