Attempting to boot the Xen kernel from FC6 (kernel-xen-2.6.19-1.2911.6.5.fc6) causes an almost immediate lockup on this hardware. The boot messages are: (XEN trace buffers disabled) Red hat nash starting <pause> Detected soft lock on CPU#0 Hardware wise, it's an HP Proliant ML110 G3 machine with nothing unusual except for an Adaptec 2410SA SATA RAID card, which works fine with the regular FC6 and earlier kernels back to FC3. I've tried "ignorebiostables" and "nolapic" as well as the grub options set by the fedora package, which are: /boot/vmlinuz-2.6.19-1.2911.6.5.fc6xen ro root=LABEL=/ noapic acpi=off quiet selinux=0 (for what it's worth, I installed this by first upgrading to FC6 and running "yum upgrade" - all working fine - then following the steps outlined in the FedoraXenQuickstartFC6 - ie I ran "yum install kernel- xen xen virt-manager") Here's /proc/cpuinfo - if there's anything else I can do or provide please let me know. processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 1 cpu MHz : 3000.866 cache size : 1024 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe constant_tsc up pni monitor ds_cpl cid xtpr bogomips : 6003.47 clflush size : 64

This report targets FC6, which is now end-of-life. Please re-test against Fedora 7 or later, and if the issue persists, open a new bug. Thanks
