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:

Kernel panic on ARM64 when running sensors-detect

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

uname -a
Linux amd-seattle-05.lab.eng.rdu.redhat.com 4.2.0-0.21.el7.aarch64 #1 SMP Tue Oct 6 15:59:59 EDT 2015 aarch64 aarch64 aarch64 GNU/Linux

How reproducible:

Use one of amd-seattle systems in lab.eng.rdu.redhat.com

Steps to Reproduce:
1. yum -y install lm_sensors
2. sensors-detect

Comment 2 Jiri Hladky 2016-04-15 21:52:51 UTC 
I have reproduced the panic also on latest kernel 4.5.0-0.33.el7.aarch64 :

[root@amd-seattle-05 ~]# uname -a
Linux amd-seattle-05.lab.eng.rdu.redhat.com 4.5.0-0.33.el7.aarch64 #1 SMP Tue Apr 5 12:55:39 EDT 2016 aarch64 aarch64 aarch64 GNU/Linux

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): modprobe: FATAL: Module cpuid not found.
Failed to load module cpuid.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): Probing for Super-I/O at 0x2e/0x2f
