I suppose this may be a moot point since Mr. R=F8sten bought a better controller, but for the record, there exists another SAS stack that als= o does not have this bug (namely, the entire lack of SATA support): http://www.kernel.org/git/?p=3Dlinux/kernel/git/jejb/aic94xx-sas-2.6.gi= t;a=3Dsummary There are various stability/functionality fixes for that stack that are under development as well: http://sweaglesw.net/~djwong/docs/sas_ata-patches/ That said, even if Mr. R=F8sten had built a driver with SATA support, h= e wrote that he had configured a RAID in the BIOS; to use that under Linux, one needs the dmraid tool to set up BIOS RAID arrays as device-mapper devices. Of course, it is possible that at least one of the many (five? six?) Adaptec 94xx driver variants supports both SATA and HostRAID natively. Better to use a nice 3ware card that takes care of all this in hardware= =2E --D - To unsubscribe from this list: send the line "unsubscribe linux-scsi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
