Therefore I doubt it'd help to have some device nodes somewhere ... Xu, all answers to your posting commented on your kernel command line. The command line you quoted contains "root =dev/ram0". You probably meant to write "root=/dev/ram0". To not waste our time, please clarify if this was a typo before asking further questions. regards, Uli -- ------- ROAD ...the handyPC Company - - - ) ) ) Uli Luckas Software Development ROAD GmbH Bennigsenstr. 14 | 12159 Berlin | Germany fon: +49 (30) 230069 - 64 | fax: +49 (30) 230069 - 69 url: www.road.de Amtsgericht Charlottenburg: HRB 96688 B Managing directors: Hans-Peter Constien, Hubertus von Streit - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
