To quote:

"""
I have encountered a serious (for me) regression with 6.18-rc2 on my
2-socket Ivy Bridge Xeon E5-2697 v2 server. After
booting, my console screen goes blank and stays blank. 6.18-rc1 was
still fine.

[...]

When I revert this from 6.18-rc2, the issue goes away and my console
screen works again.
