Well there are (at least) two reasons to do shared bus: IP over SCSI and cluster filesystems. At least for cluster filesystems I think the answer is "don't suspend your machine" for the foreseeable future - what happens if your machine goes to sleep while holding cluster FS locks, etc. I doubt any CFS vendors are going to bother to support this any time soon, since it's a HA/server feature and power management is really a desktop/laptop feature. - 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/
