Default question on a kernal "uhhuh" message

While running a long "yum update", I got the following message in the
middle:


(367/406): cscope-15.6-2.fc9.i386.rpm | 141
kB 00:01
(368/406): gstreamer-p 86% | 20% |== | 57 kB/s | 192

kB 00:12 ETA
Message from syslogd@chowder at Aug 25 11:55:03 ...
kernel: Uhhuh. NMI received for unknown reason a1 on CPU 0.

Message from syslogd@chowder at Aug 25 11:55:03 ...
kernel: You have some hardware problem, likely on the PCI bus.

Message from syslogd@chowder at Aug 25 11:55:03 ...
kernel: Dazed and confused, but trying to continue
(368/406): gstreamer-plugins-base-0.10.19-2.fc9.i386.rpm | 929
kB 00:12
(369/406): exempi-2.0.1-1.fc9.i386.rpm | 297

kB 00:03

I am assuming that the second occurrence of "(368/406):
gstreamer-plugins-base-0.10.19.2.fc9.i386.rpm" indicates that it did
finish that rpm given that the rpm_debug_check and Transaction Test
seemed to have passed.


So, I am figuring this is my computer burping somewhere. Even though it
is trying to point me at my PCI bus, I do not know what test / diags I
should be running to find out if there really is a hardware problem and,
if so, where and then how to deal with it.


Any suggestions appreciated ... if I can provide any more info, please
let me know what would be helpful.


This is related to my prior email "update error on F9 -- round two" if
more context is needed.


Thanks,
Paul

The last time I got one of these "dazed and confused" messages was
when I was running a Fedora distribution on a motherboard with
multiple PCI domains. Do you get a "dazed and confused" message
during your boot process, or did it only show up during the yum update?

Dan:

Only during the yum update. To the best of my memory, I haven't seen a
dazed and confused on this machine since I got it with FC5 back in
mid-2006 ... but I could never get it connected to the net so this is
the first time I have run yum on it.

Any RedHat compatible distribution, has a memory test included in the
first install CD.
Just boot on it, an type memtest or mem86 or memtes86 or something
like that to start the test.
Be carrefull, some VGA adapter share the begining of the memory and
this part of the memory must be
skipped to avoid false error.

Alain:

I installed off a DVD, which should be the same, so my one question
before I try this is "at what point to I get it to not do an
install/update but to give me a terminal (or single-user window) so I
can execute this command. Actually, being new to this, I don't even know
if this is something I get a terminal / single-user window for as I
don't know how early I am jumping in.


For what it is worth, I don't see any errors in the while process of
powering up the machine, but maybe the boot process isn't doing all the
tests you are suggesting.

Paul

Thanks for the clarification on Alain's suggestion. I ran the test and
it immediately failed. To make sure I was doing things right, I tried in
on another machine (which worked) and am trying it on a third machine
(which I will check in on tomorrow morning)..


Though I am not seeing any problems running on the machine that reported
the error during yum update, I am figuring "I gotta hardware problem". I
am attaching a file of my transciption of the error with the hopes of
getting some confirmation / education / advice / sympathy / etc.


Thanks for the help in teaching me where the testing stuff is on Fedora,

One of my Frankenstein boxes, made from left over computer parts, had
faulty RAM. The system would often run fine, there'd be occasional
faults. I didn't know it had faulty memory at the time, it didn't have
Linux on it, and had never been subjected to the memtest86 program. It
was much later on that it got tested, and it failed the test every time.
As an experiment, I left it running as a webserver. It continued to
work most of the time, but would occasionally die. It must have just
been luck that the faulty part of the memory wasn't being used, or was
being used by something that didn't notice the fault.

Moral of the story: A computer that apparently works fine can still
have faults, you've just not seen them yet, or not associated some
apparent software faults with actual hardware faults.

Appreciate the comment, thanks. I can live with a fault if I know
whether it is going to bite me or not later on. I've sent the memtest68
output to manufacturer to see if I can get more info (understanding that
their assumed stance will be "must replace" ... I'm just hoping to get a
"what is it?").

you go.


Is there a "memtestppc", as well?

Listing bootable images showed a "check". When I gave that a run, it
went for a while, to something more than 70% and then wandered off
into the ether -- black screen, as if it openfirmware had put it to
sleep, but it wouldn't wake up.


The Fedora 9 powerPC netinstall doesn't seem to have any alternative
images at all.
