Title:
  ubuntu_kernel_selftests.timers:threadtest fails on some bare metal

Status in ubuntu-kernel-tests:
  New

Bug description:
  In s2024.09.30 ubuntu_kernel_selftests.timers:threadtest fails on new
  bare metal hardware (amd64) for bionic:linux regression testing: metal
  instance 'cortez', and 'anonster' + 'belome' via testflinger. This is
  the first cycle that runs tests on that particular hardware, as far as
  I'm aware. The tests passes on other instances and on openstack.
