Eventually loader takes over and the system reached multi-user.

The only extra output seems to be the line
Can't get reset: -2
But, the disk was discovered successfully.
The maximum logging level was 4 out of 7, fearing bloat.

I've subscribed to the [email protected] mailing list
in case it's a better place for these questions.

Having modified sources deleted by make clean is a nuisance.
Can the behavior be avoided somehow?

Thanks for all your help!
