Hi,

Looking back into our test history at hand from this point, for this ubuntu_qrt_kernel_security ran on our openstack cloud, we can observe that:
* 6.11.0-4.4 + Test suite HEAD SHA1: bf11077d
  - Test passed on AMD64 and PPC64EL with: /dev/kmem not available ... ok
  - Test failed on ARM64, ARM64-64k with: /tmp/kmem-..../kmem: Permission denied
* 6.11.0-5.5 + Test suite HEAD SHA1: bf11077d
  - Test failed on AMD64, ARM64, PPC64EL with: /tmp/kmem-..../kmem: Permission denied
* 6.11.0-7.7 + Test suite HEAD SHA1: 0ba379b5
  - Test failed on AMD64, ARM64, PPC64EL with: /tmp/kmem-..../kmem: Permission denied
* 6.11.0-9.9 + Test suite HEAD SHA1: 4f547131
  - Test failed on AMD64, ARM64, PPC64EL with: /tmp/kmem-..../kmem: Permission denied

So I think you can say that is our initial understanding from that time
being, and it is incorrect shown to be incorrect on this point.

HTH
Thanks!

Title:
  test_032_dev_kmem from ubuntu_qrt_kernel_security failed on Oracular
  (Permission denied)

Status in QA Regression Testing:
  New
Status in ubuntu-kernel-tests:
  New

Bug description:
  Issue found on Openstack amd64/arm64/ppc64el with Oracular since
  6.11.0-5.5 in d2024.08.12.

  It's worthy to note that with 6.11.0-4.4, only ARM64 has failed with
  this test, AMD64 and PPC64EL are good.

  The test is expecting return code 6 (No such device), but we got 13
  (Permission denied) here on Oracular.

  Test log:
