Edit your /etc/grub.conf, change: timeout=0 to timeout=10 and comment out hidemenu. Next, remove quiet and rhgb. This should give you more information on what exactly hangs and when. P.S.

As far as I remember nommconf forces the kernel to ignore the PCI configuration tables - which as far as I remember, are being generated by the BIOS. (Anyone else?) I find it hard to believe that an Intel board generates broken PCI configuration tables.

As far as I know, if everything works, it means that the kernel managed to discover and configure all the PCI devices correctly and as such, I see no harm in using it. Either way, given the fact that it doesn't happen during cold boot, it looks like a hardware issue to me. I'd consider contacting your MB manufacturer. - Gilboa -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
