The patch actually merged was slightly different than the one you
mentioned.  The patch 500b55b05d0a ("PCI: Work around Intel I210 ROM
BAR overlap defect") [1] appeared in v5.17.

The best thing (if possible) would be to use a current kernel, e.g.,
v6.0.

If you can't use a current kernel, backport 500b55b05d0a to your v5.10
kernel and test that.

If you still see the problem, there's likely something more going on
that might be a different issue, so please open a new bugzilla and
attach the complete dmesg log and "sudo lspci -vv" output.
