re I'm having difficulty making teac scsi cdrom to work with aha-2940 scsi controller under kernel 2.4.19. I've tried with aic7xxx module as well as aic7xxx_old module. With aic7xxx_old the whole thing doesn't work at all, because the SCSI bus is being reset all the time. (see enclosed log file), aic7xxx module also dumps a sort of strange output and cdrom still doesn't work (cdrecord -scanbus doesn't print the right output as well as I cannot mount cdrom), although in both cases scsi controller "recognizes" cdrom. What am I missing here .. is maybe a scsi controller b0rk3n?
