Xen devel - Nov 2006 - [IPF-XenU] On Cset 12444, create/destroy Two SMP_xenU may make xen0 crashed!

Hi all,
    On Cset 12444 when creating and destroying two SMP_XenU guests, I
met xen0 crashed. I can reproduce it for many times. This problem also
existed on Cset 12425. The steps are:
1. Create 2 SMP_XenU guests at the same time;
2. When they booted up, type "xm destroy <id>", xen0 will crash.

Log is:
