Title:
  plucky: ubuntu_stress_smoke_test:dev kernel oopsed

Status in ubuntu-kernel-tests:
  New

Bug description:
  ubuntu_stress_smoke_test:dev has been throwing a kernel panic for
  plucky (6.14.0-15.15 - 6.14.0-17.17) on amd64 instances. This causes
  the rest of the test to receive a timeout afterwards.
