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 Richard W.M. Jones 2016-05-20 15:04:07 UTC 
Created attachment 1159979 [details]
output from reproducer command

Description of problem:

The RHELSA kernel hangs when running the command `sgdisk /dev/sda -U R'
apparently when rereading the partition table.  Note I am running
the kernel under qemu.

A one line reproducer for this is:

$ guestfish -N disk part-disk /dev/sda gpt : debug sh "sgdisk /dev/sda -U R" -v -x

The output from this command is attached.

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

kernel-4.5.0-0.38.el7.aarch64

How reproducible:

100%

Steps to Reproduce:
1. See one line reproducer above.
Comment 2 Tom Coughlan 2016-05-23 21:29:00 UTC 
I tried the command on bare metal and it worked as expected. 
Transferring this to the Virt. team.
Comment 3 Richard W.M. Jones 2016-05-23 21:41:07 UTC 
Hmm, weirdly now I cannot reproduce it.  Only thing I did was reboot ...
