Greetings, I have 2 machines on version 7 and I am having trouble trying an upgrade to version 8 ... already tried 8.0, 8.2 and 8 stable ... same problem, can not mount root file system on both of them. I follow the 'standard' upgrade procedure, ie, csup, buildworld, buildkernel, installkernel and reboot.I have been using the GENERIC kernel, ie, no customizations. I had the same problem on a server (dell 1650) a few months ago and ended up upgrading to 7.4, so it is a weird problem that only happens to version 8. This one machine I am doing now is a box on my desk, so I can try anything to debug it ... (it is an old IBM netfinity with a PIII and 2 scsi disks). I even tought it was somewhat related to disk, so I switched the fstab to the geom labels ... but no luck ... had the same problem. boot messages are below: da0 at ahc0 bus0 scbus0 target 5 lun 0 da0 messages ... da0 at ahc0 bus0 scbus0 target 6 lun 0 da1 messages ... Trying to mount root from ufs:/dev/da0s1a ROOT MOUNT ERROR: If you have invalid mount options, reboot, and first try the following from the loader prompt: set vfs.root.mountfrom.options=3Drw and then remove invalid mount options from /etc/fstab Loader variables: vfs.root.mountfrom=3Dufs:/dev/da0s1a vfs.root.mountfrom.options=3Drw Manual root filesystem specification: ...etc.. mountroot> <enter> pani: Root mount failed, startup aborted. cpuid=3D0 KBD: stack backtrace: #0 0xc08ebe67 at kdb_backtrace+0x47 #1 0xc08bc627 at panic+0x117 #2 0xc0943fc7 at vfs_mountroot+0x4f7 #3 0xc08737c0 at start_init+0x60 #4 0xc0890f51 at fork_exit+0x91 #5 0xc0bd5b84 at fork_trampoline+0x8 I can boot the old kernel at 7.2 and recompile again with debug flags as ne= eded. One thing I did try just now was to install 8.2 from the CD ... after I choose install options and he goes to create the filesystems I get these error messages: Unable to find device node for /dev/da0s1b in /dev! The creation of filesystems will be aborted. <OK> Couldn=B4t make filesystems properly. Aborting. <OK> thanks in advance, -Eduardo.
