[Xen-ia64-devel] Destroy VTI domain would cause Xen crashing in latest changeset 15557

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

Hi Alex and all,

 

Our nightly testing system report last night testing met Xen crashing. The problem changeset would before 15556. I think the issue was brought in by 32 side’s codes.

 

After manually checking, the crashing would happen when destroy a VTI domain.

The serial log:

(XEN) Xen BUG at event_channel.c:912x20000000200a0026, ip=0x000000006011dc10
