I have sysinstall problem since FreeBSD Curent snapshot 201010 on 
XenServer 5.6. On snapshot 201009 sysinstall is working good. Since 
201010 kernel hanging on "Timecounter "TSC frequency ... guality 800"" 
and sysinstall is never run. This bug is on amd64 and i386 platform :-(
I test sanshots 201010,11,12 and bug is in all. My procesor is AMD 
Athlon(tm) II X4 640.
