The first couple were caused by my not reading the instructions properly; theese were SCSI devices and I did get it all working OK. The big problem came when upgrading a system that was origionally a 2.1.5 system with IDE disks. The fstab file had a "wd0a" entry for the root device. I changed this to wd0s1a - which mounts OK on /dist on the 2.2.5-RELEASE system. But when I booted with my new 2.2.6-BETA kernel, it didn't even have a chance to get into single user mode. Just got mesages about "unable to mount root device" - followed by a panic and a reboot. I tried to change the "kernel root on .." entry to wd0s1a - and still the same thing. So I had to give up and revert to 2.2.5-STABLE.. The machine's miles away so it's kind of hard to test these things. Anyone got any ideas? Thanks. Scot.
