I get the same Kernel panic/reboot problem on my system as well when booting. I also followed the XenOnEdgy instructions on the wiki. Here's info for cpu1 from /proc/cpuinfo (I can provide other info if requested):
# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Xeon(TM) CPU 2.80GHz stepping : 1 cpu MHz : 2800.197 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall lm constant_tsc pni monitor ds_cpl cid cx16 xtpr bogomips : 5604.47 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 48 bits virtual power management: -- kernel panic on boot (amd64) https://launchpad.net/bugs/68987 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
