When booting 2.6 kernels on my Q650, I've also noticed the same SCSI trouble that Dana Sibera reported--
http://lists.debian.org/debian-68k/2004/08/msg00143.html I don't see unexpected IRQ's, but the rest of the driver output on the console is similar. The gist is aborting command current command pphase<freeing> cphase<clueless> aborting command current command pphase<unissued> cphase<unissued> resetting scsi bus At which point the boot hangs. The workaround I use is to power up the scsi drive containing the root filesystem immediately after telling Penguin to "Boot now". (I boot mac os from the internal drive and use an external linux root disk.) I've just confirmed that this works with 2.6.8.1. I suspect the key is that the apple drivers are not being loaded. Maybe it would be worth repartitioning using mac-fdisk instead of apple's hd setup. Do any debian m68k installers use this method? -F
