I followed the Fedora Xen Quickstart for FC5 (http://fedoraproject.org/wiki/FedoraXenQuickstartFC5)and when I booted got a message saying (approximately): Kernel panic on CPU 0 IO + APIC + timer doesn't work...try booting with the noapic option But I was already using the noapic option. I am running on a AMD Athlon 64 X2 4000+ AM2. Any help would be appreciated. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
