One other point that I'd make on this subject is that even if you had the
same kernel config file there
could be differences in the tool chain that are causing your problem. I
suspect researching that
sort of cause would use huge amounts of time and likely never lead to a
real understanding.

You can, of course, build your own kernel on Ubuntu using Gentoo source
code & config file and see
whether your new Ubuntu kernel shows the problem or acts like the provided
kernel. That might actually
produce more forward progress should you not find a more simple solution.
At least that would
presumably produce systems with the same things built in vs modules.

I would probably build vanilla-sources on the gentoo side to see if it's
Gentoo patching.

Good luck,
Mark
