[Bug 2034010] [NEW] ubuntu_bpf:test_verifier 5 failures with 5.4 kernel on s390x cloud

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Cycle: 2023.08.07
Series: focal:linux and bionic:hwe-5.4
Version: 5.4.0-162

Not a new regression, as seen last cycle (2023.07.10) on hwe-5.4
(5.4.0-156.173~18.04.1). It is the first time we have tested this on
cloud. It fails only on s390x arch.
