[Xen-ia64-devel] LTP case Crashme01 will crash Xen0.

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

Hi all,

I found a LTP case (crashme01) will crash whole Xen0 system.

My testing environment is.
====================
Xen0: RHEL4u2
Xen-IA64-Unstable: 8481
LTP version: 2005-12-5
====================

After I run crashme01, Xen0 can't get any response. Ping also failed from other 
machine. From Xen0 serial port output, I capture a BUG report of domain.c:
[root@localhost bin]# ./crash01
crash01     0  I*** xen_handle_domain_access: exception table lookup failed, iip
=f71004c8a5b4ff70, addr=f71004c8a5b4ff70, spinning...
(XEN) $$$$$ PANIC in domain 0 (k6=f000000007fe8000): *** xen_handle_domain_acces
s: exception table lookup failed, iip=f71004c8a5b4ff70, addr=f71004c8a5b4ff70, s
pinning...
(XEN) *** ADD REGISTER DUMP HERE FOR DEBUGGING
(XEN) BUG at domain.c:320
(XEN) priv_emulate: priv_handle_op fails, isr=0000000000000000

Following is the subscribing of 2 cases: crashme01 and f00f 
==============================================
f00f f00f
# This is a simple test for handling of the pentium f00f bug.
# It is an example of a catistrophic test case.  If the system
# doesn't correctly handle this test, it will likely lockup.
crash01 crash01
# Generate random code and execute it. Read f00f comment,
# this test lockup SunOS,WindowsNT,etc. in seconds..

Best Regards,
