You've trimmed the cc: list and removed intel-gfx and linux-kernel.
Don't do that, people won't see your reply otherwise. Re-added to the

If you can wire up netconsole you should be able to gather the full
backtrace and that would be really useful. Otherwise can you please
confirm by reverting that commit from your current tree that it is
