RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Amos Kong 2010-10-16 04:03:23 UTC 
Description of problem:
I try to boot up a rhel6 guest with 4 rtl8139 nics, and setup bonding in guest. When I repeatedly down/up some interfaces, guest soft-lockup.

Version-Release number of selected component (if applicable):
host kernel: 2.6.32-71.3.1.el6_0.x86_64
guest kernel: 2.6.32-70.el6.x86_64
# rpm -qa |grep qemu
qemu-kvm-debuginfo-0.12.1.2-2.113.el6_0.1.x86_64
gpxe-roms-qemu-0.9.7-6.3.el6.noarch
qemu-img-0.12.1.2-2.113.el6_0.1.x86_64
qemu-kvm-tools-0.12.1.2-2.113.el6_0.1.x86_64
qemu-kvm-0.12.1.2-2.113.el6_0.1.x86_64

How reproducible:
always

Steps to Reproduce:
1. Start guest with four nic models.
2. Setup bond0 in guest by script bonding_setup.py.
3. Run test.sh in guest to repeatedly down/up interfaces.
4. ping guest from host

Actual results:
guest soft-lookup

Expected results:
the lost packet ratio of ping is 0.

# cat bonding_setup.py
import os, re, commands

    eth_config = """DEVICE=%s

    file(eth_config_file,'w').write(eth_config)

bond_config = """DEVICE=bond0
BOOTPROTO=dhcp
ONBOOT=yes
USERCTL=no
"""
file(bonding_config_file, "w").write(bond_config)
os.system("modprobe bonding")
os.system("service network restart")

# cat test.sh  
while true;do
ifconfig bond0 down;ifconfig bond0 up
ifconfig eth2 down;ifconfig eth2 up
ifconfig eth3 down;ifconfig eth3 up
ifconfig eth4 down;ifconfig eth4 up
