RE: [Xen-ia64-devel] Xen/IPF Unstable CS#17292 Status Report

["Duan, Ronghui" <ronghui.duan@xxxxxxxxx>]

Hi Kouya,

Our QA member Amy reported few days before that Win2k3 hangs when booting. I 
find that if using Open Guest firmware and revert your patch of CS#17288, 
Win2k3 can boot. As Amy says Win2k3 can boot on Intel's firmware and I don't 
make sure that whether it is a firmware's bug but I note that you delete many 
conditions checking in your patch. I rewrite your patch base on original code 
and seem that Win2k3 can boot as normal. I am not sure whether it implements 
the purpose of your patch, could you help to check? 

I find that you include one condition that vpsr.it=0, vpsr.dt=1 which does not 
exist in original code. I am not sure whether this condition could happen in 
the real OS. If so could we support this at this time? If you can make sure 
that it is fine, could you explain that or whether I misunderstand something? 
Thanks.

Best regards
Ronghui
