Description FuXiangChun 2012-09-13 10:55:44 UTC 
Description of problem:
Boot a rhel6.4 guest with three nics(virtio e1000 and rtl8139),Sometimes Guest show call Trace when execute shutdown command 'init 0' inside guest.  I attached a Call Trace file.

host and physical info:

cpu:AMD Phenom(tm) 9600B Quad-Core Processor
# lspci |grep Ether*
3f:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5754 Gigabit 

Ethernet PCI Express (rev 02)
Version-Release number of selected component (if applicable):
# uname -r
2.6.32

guest kernel:
2.6.32-303.el6.x86_64

# qemu-kvm -version
QEMU PC emulator version 0.12.1

How reproducible:
sometimes

Steps to Reproduce:
1.boot rhel6.4 guest with three nics
qemu-kvm -M rhel6.3.0 -cpu phenom -enable-kvm -m 2G -smp 2,sockets=2,cores=1,threads=1,maxcpus=6 -usb -device usb-tablet,id=input0 -name virt-nic -uuid 9ed5a909-5c33-4bc0-960c-29ecfc61a503 -drive file=rhel6.4-virt-nic-2.qcow2,format=qcow2,if=none,id=drive-disk,cache=none,werror=stop,rerror=stop,aio=native -device virtio-blk-pci,scsi=off,drive=drive-disk,id=virtio_image,bootindex=1 -netdev tap,id=hostnet0,script=/etc/qemu-ifup,vhost=on -device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=00:24:21:7F:93:11,bus=pci.0,addr=0x4 -netdev tap,id=hostnet1,script=/etc/qemu-ifup,vhost=off -device e1000,netdev=hostnet1,id=virtio-net-pci1,mac=00:24:21:7F:93:2F,bus=pci.0,addr=0x5 -netdev tap,id=hostnet2,script=/etc/qemu-ifup,vhost=off -device rtl8139,netdev=hostnet2,id=virtio-net-pci3,mac=00:24:21:7F:93:3E,bus=pci.0,addr=0x6 -vnc :3 -device sga -chardev socket,id=serial1,path=/var/test6,server,nowait -device isa-serial,chardev=serial1 -bios /usr/share/seabios/bios-pm.bin -boot menu=on -monitor stdio -qmp tcp:0:6666,server,nowait

2.shutdown guest inside guest
#init 0
3.get call Trace info from console in host
#nc -U  nc -U /var/test6
  
Actual results:
sometimes guest call trace

Expected results:
shutdown successfully

Hi Xiangchun,

Can you help to test with non kvmclock?

Is it a RHEL kernel? What's the output of '# uname -a', '# rpm -q kernel'

> guest kernel:
> 2.6.32-303.el6.x86_64

Please use latest kernel in brewweb in new test.

It's better to provide kvm version info by "# rpm -q qemu-kvm"

If reinstall guest and update kernel with the latest kernel.  I cann't reproduce this bug. I am continuing to confirm this issue. Any testing results I will update to bz.
