Bug Description

Issue found on Intel node "vought" with:
  * 5.13.0-28.31
  * 5.13.0-27
  * And possibly the 5.13.0-23 from the last cycle (this test didn't finish properly and marked as "Incomplete" back then, just like this cycle). For more earlier Impish kernels, this system was not tested with this test on them.

The test will hang with unshare test in ubuntu_stress_smoke_tests:
12:39:39 DEBUG| [stdout] udp RETURNED 0
12:39:39 DEBUG| [stdout] udp PASSED
12:39:39 DEBUG| [stdout] udp-flood STARTING
12:39:41 DEBUG| [stdout] udp-flood RETURNED 0
12:39:41 DEBUG| [stdout] udp-flood PASSED
12:39:41 DEBUG| [stdout] unshare STARTING
(Test hangs here)

And eventually the test will be killed because of the timeout setting.

In a duplicated report (bug 1962551), Colin mentioned that this could be a kernel issue.

This issue can be found on focal OEM-5.14.0-1025.27 with Intel node vought, also Jammy 5.15.0-22-generic.
