If its that long and complicated, it has to work ;-) I've been at this literally since breakfast, so I think I'll call it a day for tonight, but I will give that a try and file the bug report, too. I'll include your email address in the CCs. Merci a lot. I sure hope it works! That old laptop is still as good as new, practically. I'd hate it to be bricked. I suppose I could go back to F23, if TPM hasn't gotten hardware switched somehow. -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@xxxxxxxxxxxxxxxxxxxxxxx
