Once you get "cannot assemble drivers for root", it's over. That error is fatal. A few lines later you see a panic "vfs_mountroot: cannot mount root" which is the normal endpoint for driver/hardware mismatch.
hrm. Any pointers/tips on how to proceed?
If I'm able to get it to the "Running in command line mode" point with openbios, and it seems to hang there, is this just silently having related problems or do I just need to wait longer?
