After several seconds of silence, lots of these appeared: devfs_dealloc_unique_number(): number 128 was already free devfs_dealloc_unique_number(): number 128 was already free By the way, that scsi_debug_many_disks.tgz tarball contains: drivers/scsi/scsi_debug.h drivers/scsi/scsi_debug.c This driver is valid for any kernel in the lk 2.4 series. If the tarball is unzipped in /usr/src/linux it would replace the originals (which is no great loss but you may like to keep copies of them). Also my .config contains: CONFIG_SCSI_DEBUG=m (for GUI users it is the last SCSI adapter listed). Doug Gilbert
