Ok, this is a BIOS bug - we have a recommendation about what the BIOS
should do but yours doesn't do it. Are you sure you're using the latest
BIOS for your motherboard?

Can you check for updates and if you get a newer version, can you update
your BIOS and do the two commands above?

If there's no newer BIOS, we can try applying the workaround at boot in
an init script to fix your issue.
