Red Hat Bugzilla – Bug 206188
[rhel4 u6] reboot fails on IBM System x336
Last modified: 2007-11-16 20:14:53 EST
Description of problem:
We have recently started to use Redhat Enterprise v4 update 4 on i386 and x86-64
systems. With the change from EL3 we have noticed that most of the systems fail
to reboot with a simple 'reboot' command. In each instance we get the following

It then gets to that point and fails to reboot every time. I have attempted to
install the Operating from CD (our default is to kickstart the servers) and it
also fails. The way I have resolved the issue is to append the following
information to the kernel boot parameters : acpi=noirq
Once that has been added the system restarts every time. It is very similar to
the following redhat buzilla #182961
We are using in this instance the IBM System X (X Series) 336 servers with the
latest firmware/bmc etc from IBM.
Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
Kernel 2.6.9-42.0.2.ELsmp on an i686
Install Redhat Enterprise v4 Update 4 on an IBM x336, then attempt to restart
the system using init 6 or reboot and the system will fail to reboot giving the
What is the model? 8837,1879, or 7978?
The model that we are having problem with is as follows 8837. If we need to we
could probably put a demo system on a public IP for you to have a play with.
My records indication that the latest BIOS is v33A (APJT33A). BMC is v24A
is(APBT24A) . Can you verify that you have the same version?
We have the following software revisions installed on the servers that have been
BIOS : v1.13
BMC : v1.15
These are the revisions that IBM have been shipping servers with in recent
months, When I checked the software updates on the IBM.com web page they are
reported as being current.
Those are the latest and greatest numbers. I do not have access to this machine
locally but I have let an IBM person know about this and asked him to reproduce
The IBM person was able to sucessfully reboot the machine. I have asked them to
provide with a 'sysreport' report so that I can compare his machine to yours.
Can you also run 'sysreport' and attach the tar ball to this BZ? Thank you.
Can you check if 'aarich' module is loaded? If it is, can you rmmod it and then
try to reboot, please? Thanks
James, any update?
there are no aarich modules loaded on this server. The RAID card in question is
(sorry about the long delay I have been on leave).
Thanks for your response. Can you attach the sysreport to this BZ pls? Just run
'sysreport' and uplaod the tarball it creates. Thanks.
Any update on running the command?
I am closing this BZ as DEFERRED. James, pls re-open this and upload the tarball
from running sysreport.
