Has anyone had experience (or even success) with the current 2.4.x kernels, ide-scsi burners, and cdrdao writing faster than 16x?
True SCSI CD burners are becoming rare, except for older, slower models. So in a new Red Hat 7.2 machine, I tried hooking up a Yamaha CRW3200E (24x10x40, EIDE) and connecting via the ide-scsi module. cdrdao succeeds, albeit very slowly. I suspect that if there weren't underrun protection in the burner, I'd have a bunch of coasters. Indeed, simulation runs fail anything I try writing faster than 12x. I've tried building a 2.4.17 kernel with the same results (see below).
