Note that the problem can also be (mostly) worked around by upgrading to a kernel with the checksum fix (#88986 (comment)) or by disabling checksum offload on the relevant network interfaces (eg, #88986 (comment) gives the command for flannel; some of the other xref'ed bugs may give the exact commands for other plugins if you can't figure it out).
