Description Kathy Whyte 2006-08-10 17:44:40 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; InfoPath.1)

Description of problem:
Processor/s: Dual Processor - Dual AMD Opteron 285 2.6
GHz 64-Bit w/ Dual Core Technology
Motherboard: Tyan® Thunder K8WE Motherboard w/ SLI Support
8 GB RAM, 8 GB swap 

The machine seems to run fine when not loaded, but when
performing a CFD calculation that uses about 4 GB of RAM
it will lock up at random times where it does not respond
and the caps lock and scroll lock light will flash on and
off together about every second. 

System will run longer with two iterations than with four.
Has tried disabling dual core no improvement.

Sometimes when the system locks up the keyboard lights do not flash.

Dual boot windows and Linux system...

Version-Release number of selected component (if applicable):
kernel 2.6.9-34.0.2ELsmp

How reproducible:

Steps to Reproduce:
1.boot computer
2. run job(s) to about 4.6G RAM useage
3. Computer hangs with lights sometims blinking sometimes not.

Actual Results:
Computer hangs with lights sometims blinking sometimes not.

Expected Results:
should be able to run through the job(s) properly.

Additional info:
Runs a job fine on same system under windows.

Comment 2 Jason Baron 2006-08-11 11:26:04 EDT
Can you please post any messages from /var/log/messages, that appear at the time
of the crash. When the machine locks up, can you do alt-sysrq-t. this will
hopefully dump the state of all the processess. thanks.
Comment 3 Dan Carpenter 2006-08-11 12:30:01 EDT
For some reason everything after the 1.01 BIOS on this set up the interrupts as
edge triggered instead of level triggered.  Only the 1.01 bios will work under

Tyan says that if you use a kernel later than 2.6.14 the interrupts are set up
correctly.  I haven't seen anything that important change between 2.6.13 and
2.6.14 so i couldn't swear that they didn't just change a something in the
.config file...

Anyway, I'm working with their BIOS team and hopefully they'll get this fixed soon.

Created attachment 134075 [details]
patch to match upstream kernel

I think I've got it...	This is the same as the upstream kernel.

The PCI devices in /proc/interrupts are level triggered now.
Comment 5 Kathy Whyte 2006-08-15 14:44:22 EDT
I have updated the kernel to version 2.6.9-42.ELsmp that 
    was released last week.  The machine still exibited the 
    lockup issue with the new kernel. It still has bios 
    version 1.03, but by default the HT-LDT Frequency is set 
    to auto which when the machine boots it says the HT-LDT 
    Frequency is 1000MHz. I changed the setting in the bios 
    from auto to 800MHz and it seems to run now, as my 
    calculations ran all night last night and today with no 
    problems.  What is this HT-LDT freqency?  Thanks

Comment 6 Jim Paradis 2006-08-16 16:13:38 EDT
The patch listed in Comment #4 is similar to something I saw in RHEL3.  I'll
test it out and post it.
Comment 7 Jim Paradis 2006-08-16 17:08:48 EDT
Patch tested and posted to rhkernel-list
Comment 8 Kathy Whyte 2006-08-18 09:07:39 EDT
I thought I had the problem resolved, but
as soon as I say somthing, it locked up again. When I
returned from lunch, the caps lock and scroll lock lights
were flashing and the machine had locked up after running
for ~2 days with no issues!

Comment 9 Kathy Whyte 2006-08-21 14:10:52 EDT
Interestingly, the machine locked up over the weekend with
BIOS version 1.01. It did run for about 1.5 days before
it locked up, and as before the scroll lock and caps lock
lights on the keyboard were flashing.

Comment 10 Kathy Whyte 2006-08-21 14:13:56 EDT
Ron is my user whom I am trying to assist with this issue.
Where do we need to go next with this?
I've not done a kernel recompile in years and on linux only added a module that
was already available and that was also years ago.
My user needs resolution as soon as possible.

Thanks for your attention and assistance to date and in the future.

Comment 11 Jim Paradis 2006-08-21 14:17:34 EDT
The patch listed in Comment #4 is not part of the 2.6.9-42.ELsmp kernel.  It has
been proposed for possible inclusion in a future kernel release.
Comment 12 Jason Baron 2006-08-29 14:33:31 EDT
committed in stream U5 build 42.3. A test kernel with this patch is available
from http://people.redhat.com/~jbaron/rhel4/
Comment 13 Kathy Whyte 2006-10-03 12:52:05 EDT
My current kernel is 2.6.9-42.14.ELsmp and BIOS is
1.04.2895. The motherboard is a Tyan Thunder K8WE Model
S2895 running BIOS version 1.04.

The above system still locks up...

I have two machines with IWILL motherboards and dual single
core Opteron 248's that runs fine.
