failed test log

Description of problem: The cpuscaling test abort during the test on RH 5.6 on x86 using intel Pentium(R) CPU G630 with v7-1-3-46 but pass with v7-1-2-25



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

RH5.6 v7-1-3-46 

How reproducible: Every time

Steps to Reproduce:
1. Install proc listed above in a DL120 G7. Latest rom. 
2. Execute cpuscaling 

  
Actual results: Test abort


Expected results: Pass


Additional info:Same system/rom/proc passes x64 successfully

Garry is this repeatable?  Unfortunately I don't see anything that helps determine the issue in the logs except what appears may be a duplicate of bz#722384.  What information is in /sys/devices/system/cpu/* ?

Hi Rob,

See attached cpu.zip. Yes, it's repeatable.

Thanks for your support.

Regards,

Garry

Hi Garry,  I suspect the cpu topology is being reported wrong in the kernel as it current defines every CPU as no relation to any other core.  This data I thought was provided by the BIOS to the kernel, but also in RHEL5 I believe the -xen kernel can mask the topology in a DOM.  Does this same problem occur on the BM kernel?

Hi Rob,

Yes, Hi Rob,

Yes, this same problem occurs on the BM kernel.

Thanks,

Comment 8 Rob Landry 2011-12-12 16:18:43 UTC
Hi Garry,  is this issue still occurring?  The topology is reported by the kernel so I don't think there's much we can alter in v7 to resolve; however the cpuscaling test did receive a fairly large update in v7-1.4.
