I have an LSI controller on PCIe (4x electric), plugged on second PCIe 16x slot.

I had to unplug it to flash back to 403.

I hope that the guy that posted it will report to Asus BIOS engineers this big bug of 406.
I hate 0406. I had the same issue with adaptec 3405 raid controller. Good to hear that I was not alone. Since 0406 has incompatibility issue not only with adaptec, i hope asus will solve the problem quickly.
