Hi,
all stable release queues from v4.9.y up to v5.4.y have boot stall problems. The culprit is the backport of commit d7ea0d9df2a6 ("net: remove two BUG() from skb_checksum_help()"), specifically the following code.
Not sure why this patch has been backported.
It had no Fixes: tag, and was not a stable candidate.
Happens with lots of patches. Never ending discussion.

While that works fine in the upstream kernel since ret is subsequently always overwritten, that is not the case in older kernels. In those, the function now always returns -EINVAL.
