Description Min Deng 2012-08-09 02:32:17 EDT
Description of problem:
Coredump occurred while system_reset guest which was undergoing heavily press.

Version-Release number of selected component (if applicable):

How reproducible:
Steps to Reproduce:
1.boot up guest with the CLI
  /usr/libexec/qemu-kvm -m 2G -smp 4 -cpu cpu64-rhel6,+x2apic,family=0xf -usb -device usb-tablet -device virtio-scsi-pci,id=scsi0 -drive file=win7-32-scsi.qcow2,format=qcow2,if=none,id=drive-virtio0,cache=writeback,werror=stop,rerror=stop,serial=systemdisk -device scsi-hd,bus=scsi0.0,drive=drive-virtio0,id=virtio-blk-pci0,bootindex=1 -netdev tap,sndbuf=0,id=hostnet0,script=/etc/qemu-ifup,downscript=no -device e1000,netdev=hostnet0,mac=00:12:27:44:27:18 -uuid 57d734cb-bdf2-44d7-b750-9dff30e9d46b -no-kvm-pit-reinjection -chardev socket,id=111a,path=/tmp/monitor-win732-scsi,server,nowait -mon chardev=111a,mode=readline -rtc base=localtime,clock=host,driftfix=slew -chardev socket,id=seabios_debug,path=/tmp/monitor-seabios,server,nowait -device isa-debugcon,iobase=0x402,chardev=seabios_debug -device virtio-scsi-pci,id=scsi1 -drive file=disk1.qcow2,if=none,format=qcow2,cache=writeback,id=drive-virtio-data1,werror=stop,rerror=stop,serial=disk1data -device scsi-hd,bus=scsi1.0,id=virtio-data1,drive=drive-virtio-data1 -device virtio-scsi-pci,id=scsi2 -drive file=disk2.qcow2,if=none,cache=writeback,format=qcow2,id=drive-virtio-data2,werror=stop,rerror=stop -device scsi-hd,bus=scsi2.0,id=virtio-data2,drive=drive-virtio-data2 -device virtio-scsi-pci,id=scsi3 -drive file=disk3.qcow2,cache=writethrough,if=none,format=qcow2,id=drive-virtio-data3,werror=stop,rerror=stop -device scsi-hd,bus=scsi3.0,id=virtio-data3,drive=drive-virtio-data3 -device virtio-scsi-pci,id=scsi4 -drive file=disk4.qcow2,if=none,format=qcow2,cache=writethrough,id=drive-virtio-data4,werror=stop,rerror=stop -device scsi-hd,bus=scsi4.0,id=virtio-data4,drive=drive-virtio-data4 -bios /usr/share/seabios/bios-pm.bin -spice port=5931,disable-ticketing -vga qxl -monitor stdio -qmp tcp:0:4444,server,nowait
2.please run multiple Crystal Disk Mark Apps on the five disks in order to give heavily press for the guest for reproducing
  Notes,the size of the guest image about 30G and each data disk about 2G. 
3.then do S4 (install qxl driver for the guest beforehand)
4.do system_reset from monitor 

Actual results:
Users can wake up guest,or via system_reset from monitor,the guest can reboot successfully
Expected results:
After system_reset,the guest became to black screen and at last,Core dumped happened.
(qemu) system_reset
(qemu) Segmentation fault (core dumped)
