Ah, so it's just me then... ;-) Well, I'll post this for future reference... I've compiled a new version of my working kernel (-1.12_FC2smp) and tried to boot from it... and I get the same problem! But I also noticed that on a successful boot, I get Red Hat nash version 4.1.18 starting Mounted /proc filesystem Creating /dev Starting udev Loading scsi_mod.ko module SCSI subsystem initialised Loading sd_mod.ko module Loading aic7xxx.ko module ...and then here I get all the info related to my SCSI interface booting, followed by... Loading jdb.ko module Loading ext3.ko module Creating root device Looks like this could be a SCSI problem?
