Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 of problem:
RHEL5.6 crash during boot.

Version-Release number of selected component (if applicable):
kernel version: 2.6.32-130.el6.x86_64
qemu version: qemu-kvm-0.12.1.2-2.156.el6

How reproducible:
sometimes

Steps to Reproduce:
1. Run commands on host:
grep -q el5 /proc/version && ([ -e /dev/ksm ] && true || modprobe ksm && ksmctl start 5000 50 ) || (echo 1 > /sys/kernel/mm/ksm/run && echo 5000 > /sys/kernel/mm/ksm/pages_to_scan && echo 50 > /sys/kernel/mm/ksm/sleep_millisecs); echo 'never' > /sys/kernel/mm/redhat_transparent_hugepage/enabled

2.start vm with command:
qemu -name 'vm1' \
-chardev socket,id=qmp_monitor_id_qmpmonitor1,path=/tmp/monitor-qmpmonitor1-20110411-111144-vdyn,server,nowait \

I am trying to reproduce this bug with autotest, hope it will have a result tomorrow.

If you can reproduce it verify that it is still reproducible 1) with ksm disabled, 2) without usb tablet. Note: check only 1 or 2 not both simultaneously.

Hi, Gleb,
I am trying to reproduce this problem as your advice, but seems it will take
a little more time, it's hard to reproduce.
Comment 6 Qingtang Zhou 2011-04-18 07:05:28 UTC 
Hi,
I tried to boot RHEL4.9 guest for about 200 times, but no kernel panic occured again.

Why RHEL4.9? The bug title talks about rhel5.6.

Sorry, type error, my fault. I mean it's RHEL5.6.
Comment 10 Gleb Natapov 2011-04-20 08:44:56 UTC 
Closing the bug since it is not reproducible. Reopen if you see it again.
