The fixes I wrote for the data corruption bug in the mac_scsi driver have been sent upstream and will appear in the v5.3 release which is expected in a few weeks. I've also backported all of my driver patches to the 4.14.y stable branch. A patched v4.14.137 kernel build (configured for Mac only) is available -- https://sourceforge.net/projects/linux-mac68k/files/ This binary has all of the important drivers built-in so it requires no initrd to boot a Mac from hard disk, CD-ROM, NFS rootfs, etc. (It can also be used with the Debian installer initrd.) Chris, regarding the compatibility issue affecting your ADTRON SDDS device and the mac_scsi driver: the driver should now fall back to PIO automatically (without corrupting data). Note that PDMA is around 5 times faster than PIO (on a IIfx). So you may want to use a different disk with your SE/30. The latest mac_scsi driver was tested with a wide range of targets. HTH. --
