Should be set to 1.1. 1.4 does not work well.

That is the first thing to check when system hangs start occuring. It is a tiny boot floppy/CD that will show you where there are problems. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
