Please could you give this a go. It is totally untested, not even
compile tested...

Sure. The system boots but ther is one splat:

this is a known issues since 4.20 [1], [2]. So not related to the crash.

Oh, I see.

Unfortunately, you didn't wrote which kernel version works for you
(except of this splat). Only 5.3 or 5.4-rc3 too?

With v5.2.20 I was able to boot the system. But after this discussion
I would say that was just luck. The race seems to exist for longer and
only with my 'special' config I am able to reproduce it.

okay, let me rephrase my question. You said that 5.4-rc3 didn't even
boot in your setup. After applying Andrew's patch, does it boot or is it
a different issue?

Hi Stefan

I would say i fixed a real issue with my patch. I will submit it to
David for stable. The problem has come to light because Danial is
using the kernel ipconfig and NFS root. That makes the race condition
hit every time. But the issue could happen under other conditions as
well.
