Try adding "pci=nocrs" to the boot options. I had the same issue, same kernel and 64-bit system. Changing the BIOS SATA setting from ACHI to ATA resulted in a successful boot & system operation. I did not try "pci=nocrs". Did "nocrs" fix the problem? Created attachment 443082 [details]
lspci -vvv output from Dell T3500
Reverting the BIOS to SATA / AHCI, the hang recurred. And "pci=nocrs" *did* fix the problem. BTW, the machine is a Dell T3500 desktop using the latest A07 BIOS. I've attached the lscpi -vvv output.
Use of _CRS will be disabled by default in the next update. kernel-2.6.34.6-54.fc13 has been submitted as an update for Fedora 13. https://admin.fedoraproject.org/updates/kernel-2.6.34.6-54.fc13 I think this is a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=620313 or possibly https://bugzilla.kernel.org/show_bug.cgi?id=17011 A complete dmesg log from the "pci=nocrs" boot would be enough to tell for sure. There's a little more discussion and a debug patch at bug 620313. kernel-2.6.34.6-54.fc13 has been pushed to the Fedora 13 testing repository.

After "yum update", which installed a new kernel, next boot greeted me with "dracut: FATAL: No or empty root= argument" and hung on boot. I rebooted a few times to make sure it is reproducible, then rebooted into previous kernel, which booted ok. I did not edit my grub.conf, and the sections for both new and old kernels look similar: title Fedora (2.6.34.6-47.fc13.x86_64) root (hd0,0) kernel /vmlinuz-2.6.34.6-47.fc13.x86_64 ro root=/dev/mapper/vg_dhcp25227-lv_root rd_LVM_LV=vg_dhcp25227/lv_root rd_LVM_LV=vg_dhcp25227/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet initrd /initramfs-2.6.34.6-47.fc13.x86_64.img title Fedora (2.6.33.6-147.2.4.fc13.x86_64) root (hd0,0) kernel /vmlinuz-2.6.33.6-147.2.4.fc13.x86_64 ro root=/dev/mapper/vg_dhcp25227-lv_root rd_LVM_LV=vg_dhcp25227/lv_root rd_LVM_LV=vg_dhcp25227/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet initrd /initramfs-2.6.33.6-147.2.4.fc13.x86_64.img
