--- Comment #2 from Mitchell Horne <mhorne@freebsd.org> ---
Hi Jari,
Thanks for your efforts in identifying this. I worked on this problem a while
ago when I was hacking on the JH7100. Back then I created a revision that fixed
the problem on riscv, see https://reviews.freebsd.org/D34118. It contains my
own description of the problem and why it has been unlikely to manifest in most
other cases.
Our changes appear to be the same, differing only stylistically. I would be
happy to help land either version of the fix.
Do you have an account on reviews.freebsd.org? That would be the best place to
submit these changes for wider review and eventual inclusion in the tree.
Bugzilla makes code contributions difficult.
