Thread-topic: "xm destroy" causing x86_64 Xen to crash 
I find that when I force a DomU to crash (for example by specifying an
incorrect root= option) and then do an "xm destroy" on the DomU, Xen
crashes. This happens only with SMP DomU.

This is with x86_64 Xen (changeset 6714) on a Dell PowerEdge 470 (4x
with HT) and 2GB RAM running SLES9 SP2.

Isn't smp_send_stop() happening on all VCPUS????

DomU Crash
----------
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
