RE: [Xen-ia64-devel] [PATCH] Allow multiple-time mmap of the privcmddevice

["Zhang, Xiantao" <xiantao.zhang@xxxxxxxxx>]

Hi Yamahata,
        Although I have booted up VTi with VP mode, seems that it is not stable 
yet. After creating for about 2 hours, it will panic without any workload on it.
Did you see the same issue?. Once capture the log, I will send it to you. :) 
Thanks
