Errors with BIOS 1.2.3/1.2.5

So there have been multiple posts regarding errors with the BIOS 1.2.3+ i.e. audio aracking for a few seconds, games crashing, over-heating and all posts are asking to downgrade the BIOS to 1.2.2 or below. I am not very comfortable doing so because I have a Dual Boot that uses Grub and I don't want the Laptop to break. For those having the issues, this would be happening on Inspiron 5570 or Inspiron 5770.

I just wish to know if Dell wishes to fix this in the next BIOS update. If yes, then how soon can we see it?

My fellow Inspiron Users please tag Dell admins /ask for support so that we can see this happen soon.
