I think I'd go along with that. I recently upgraded from a version of 3.0-current just before Christmas last year to the latest version. Since then, without changing the configuration file, I'm getting lots of these messages: Jul 30 13:36:31 freebie /kernel: aha0: DMA beyond end Of ISA: 0x3183d14 Jul 30 13:36:32 freebie /kernel: aha0: DMA beyond end Of ISA: 0x3354d14 Jul 30 13:47:48 freebie /kernel: aha0: DMA beyond end Of ISA: 0x3394d14 Jul 30 13:47:50 freebie /kernel: aha0: DMA beyond end Of ISA: 0x31bfd14 Of course I have BOUNCE_BUFFERS set in the config file. In addition, lots of spurious error messages are caused by my Archive DDS changer. It got so bad (for some reason the driver wasn't able to read or write the tape) that I had to hang it on the 2940 which I usually reserve for disks (where it works perfectly). I'm copying this to -scsi, since it really beloings there. Greg
