I just wanted to report that I am not having problems at all, BIOS, Grub menu, single user and multiuser all work just fine. Another possibility for why it is not working for the originator of this thread is the USB chipset. Having worked at some HW integration companies that were using various chipsets from different manufacturers, all USB chipsets do not behave the same way, and some require a rather frequent HW poll that consumes quiet a bit of bus bandwidth. Perhaps the originator of this thread is really experiencing a USB HW issue. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
