In net-next there's the following patch which mentions in the

And spurious list pointer poisoning is what we see here (IMO).

As an idea this patch and a8305bff6852 ("net: Add and use
from net-next could be applied on top of 4.19. Would be curious
whether it fixes the issue.

Applied both, still panics. %r12/%r15 are still poisoned too.
