I tried reproducing the issue on a local VM with the same kernel (not a AWS instance) but I was not able to reproduce it.
If possible, could you provide me with a AWS instance for me to test for myself? If not, could you run "sudo bash posix_mq.sh -r", paste the contents of the test directory it leaves behind (Files retained in: /tmp/sdtest.*) and the dmesg messages?

Title:
  posix_ipc test from test_regression_testsuite of ubuntu_qrt_apparmor
  failed with F-aws-5.15 T3A (could not mq_notify: Connection timed out)

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

Bug description:
  Issue found on AWS AMD 64 instance t3a.2xlarge with:
   * F-aws-5.15.0-1053.58~20.04.1
   * J-aws-5.15.0-1053.58 

  This is reproducible, 4 out of 4 attempts on
  F-aws-5.15.0-1053.58~20.04.1

  There is no such issue on t3a.2xlarge with
  F-aws-5.15.0-1052.57~20.04.1 nor J-aws-5.15.0-1052.57. Therefore it
  appears to be a possible regression.

  The posix_ipc test in test_regression_testsuite will fail with:
    Error: posix_mq_rcv failed. Test 'POSIX MQUEUE (confined receiver root - unconfined sender : mq_notify)' was expected to 'pass'. Reason for failure 'FAIL - could not mq_notify: Connection timed out'
