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 Dr. David Alan Gilbert 2017-03-02 11:35:42 UTC 
Description of problem:
(Split out of 1411275)
Repeatedly rebooting a rhel6 machine type guest will result in a hang about 1 in 20 or so times.

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


How reproducible:
~1/20 times

Steps to Reproduce:
1. Take a 6.9 guest
2. Start it with:
/usr/libexec/qemu-kvm \
-name rhel7 \
-S -machine rhel6.6.0,accel=kvm,usb=off,smm=off \
-realtime mlock=off \
-cpu Opteron_G3 \
-sandbox off \
-m 7680   \
-smp 1, \
-uuid 49a3438a-70a3-4ba8-92ce-3a05e0934608 \
-no-user-config \
-nodefaults \
-rtc base=utc,driftfix=slew \
-global kvm-pit.lost_tick_policy=discard \
-no-hpet \
-no-shutdown \
-global PIIX4_PM.disable_s3=1 \
-global PIIX4_PM.disable_s4=1 \
-boot order=c,menu=on,splash-time=3000,strict=on \
-drive file=rhel-guest-image-6.9-28.x86_64.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,serial=f65effa5-90a6-47f2-8487-a9f64c95d4f5,cache=none,discard=unmap,werror=stop,rerror=stop,aio=threads \
-device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x9,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 \
-chardev stdio,mux=on,id=mon -mon chardev=mon,mode=readline --device isa-serial,chardev=mon \
-k en-us \
-device VGA \
-chardev file,id=bioslog,path=bioslog \
-device isa-debugcon,iobase=0x402,chardev=bioslog \
$*

3. repeatedly log into the guest and type 'reboot'

Actual results:


Expected results:


Additional info:
Already debugged to the 'TimerLast' variable overlaying the code in Seabios and getting incremented before boot.

Comment 12 FuXiangChun 2017-04-27 10:11:34 UTC 
According to comment0,QE tried to reproduce with different host & unfix seabios seabios-1.9.1-4.el7.x86_64. and Guest reboot continuously for 2 hours. Guest still works well. So, see if QE can do some sanity test to verify this bug? e.g Guest reboot continuously with fixed seabios version(seabios-1.10.2-2.el7) for 24 hours. If guest still works well then we think this bug is fixed.

Yes, if it's rebooting well then that's fine; it doesn't need 24h, 100 reboots should do.

Verified bug with fixed seabios version seabios-1.10.2-2.el7.x86_64. >100 reboots.  guest works well. so set this bug as verified.
