** Description changed:

- On azure-fips platforms multiple tests in ubuntu_ltp,
- ubuntu_ltp_controllers, ubuntu_ltp_cve, and ubuntu_ltp_syscalls are
- causing the system to be unresponsive. When running locally the tests
- run to completion but the system hangs sometime after.
+ In sru-s20240429 and sru-s20240610, the ubuntu_ltp_* tests were found
+ unable to finish properly with B-azure-fips kernel, and eventually
+ trigger the `sut-test` failure on them.
+ 
+ Here is the result from sru-s20240610
+ * ubuntu_ltp
+   - report cuts-off at fs:fs_fill test, failed on Standard_D4_v4 only.
+ * ubuntu_ltp_controllers
+   - report cuts-off at memcg_test_3 test, failed on Standard_B1ms
+   - report cuts-off at memcg_stress test, failed on Standard_D4_v4, Standard_D4s_v3-gen2
+ * ubuntu_ltp_cve
+   - report cuts-off at cve-2016-8655 test, failed on Standard_B1ms, Standard_D4_v4
+   - report cuts-off at cve-2018-18559 test, failed on Standard_D4s_v3-gen2 
+ * ubunut_ltp_syscall
+   - report cuts-off at setsockopt06 test, failed on Standard_B1ms
+   - report cuts-off at bind06 test, failed on Standard_D4_v4, Standard_D4s_v3-gen2
+ 
+ The result from sru-s20240610 is quite similar, just the ubuntu_ltp_cve
+ this time cuts-off at cve-2016-8655 test on Standard_D4s_v3-gen2.
+ 
+ Note that the cve-2016-8655 is actually the setsockopt06 test, and
+ cve-2018-18559 is the bind06 test.
+ 
+ I have done some experiments on Standard_D4s_v3-gen2 with kernel in sru-s20240610 (4.15.0-2088-azure-fips):
+ * ubunut_ltp_controllers:
+   - If we skip memcg_stress test, it will be able to finish properly.
+ * ubuntu_ltp_cve:
+   - If we skip cve-2016-8655 and cve-2018-18559 tests, it will be able to finish properly.

Title:
  ubuntu_ltp_* tests unable to finish properly with B-azure-fips

Status in ubuntu-kernel-tests:
  New

Bug description:
  In sru-s20240429 and sru-s20240610, the ubuntu_ltp_* tests were found
  unable to finish properly with B-azure-fips kernel, and eventually
  trigger the `sut-test` failure on them.

  Here is the result from sru-s20240610
  * ubuntu_ltp
    - report cuts-off at fs:fs_fill test, failed on Standard_D4_v4 only.
  * ubuntu_ltp_controllers
    - report cuts-off at memcg_test_3 test, failed on Standard_B1ms
    - report cuts-off at memcg_stress test, failed on Standard_D4_v4, Standard_D4s_v3-gen2
  * ubuntu_ltp_cve
    - report cuts-off at cve-2016-8655 test, failed on Standard_B1ms, Standard_D4_v4
    - report cuts-off at cve-2018-18559 test, failed on Standard_D4s_v3-gen2
  * ubunut_ltp_syscall
    - report cuts-off at setsockopt06 test, failed on Standard_B1ms
    - report cuts-off at bind06 test, failed on Standard_D4_v4, Standard_D4s_v3-gen2

  The result from sru-s20240610 is quite similar, just the
  ubuntu_ltp_cve this time cuts-off at cve-2016-8655 test on
  Standard_D4s_v3-gen2.

  Note that the cve-2016-8655 is actually the setsockopt06 test, and
  cve-2018-18559 is the bind06 test.

  I have done some experiments on Standard_D4s_v3-gen2 with kernel in sru-s20240610 (4.15.0-2088-azure-fips):
  * ubunut_ltp_controllers:
    - If we skip memcg_stress test, it will be able to finish properly.
  * ubuntu_ltp_cve:
    - If we skip cve-2016-8655 and cve-2018-18559 tests, it will be able to finish properly.
