You have ext[234] filesystems builtin. I suppose the rootfs is one of those?

Your .config file also has the ATA drivers as =m (loadable modules), but
I guess that you also tested with those drivers =y (builtin).

I don't see what the problem is.
You may need to try taking a photo of the failed boot and sending it to
the mailing list (and me) again, even though that has not worked for you
some time in the past.
