That's the simplest way as you must have some custom hardware that doesn't like this, so a custom-configuration seems like the best option. Did you try that and it did not work? What is the problem of EISA at boot anyway? thanks, greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
