RE: [Xen-ia64-devel] Weekly benchmark results [ww24]

["You, Yongkang" <yongkang.you@xxxxxxxxx>]

Hi Fujita,

I tried the latest Changeset 10419. But I couldn't reproduce this problem in my 
box. Is it fixed? I create and destroy SMP XenU for more than 100 times. And 
try to make kernels in xenU 2 times. I didn't meet the xen0 hang.

My box has 3072M memory. Xen0 has 512M, xenU has 512M. XenU has been assigned 
with 2 CPUs.

Best Regards,
Yongkang (Kangkang) 永康
