Compiling kernel modules fails for 6.4.0
I'm trying to built kernel modules on 6.4.0 for a readynas 516. I've got the source from http://www.downloads.netgear.com/files/GPL/ReadyNASOS_V6.4.0_WW_src.zip and am using the kernel from the directory linux-4.1.7-x86_64. No matter what I try, modprobe always ends up complaining "invalid module format". In dmesg I see "no symbol version for module_layout". Unfortunately this happend before, the last time this happend (on 6.1.9) the included kernel/config in the zip was wrong ( see https://community.netgear.com/t5/Community-Add-ons/Compiling-kernel-modules-for-6-1-9-fails/td-p/958206 ) -- is this again the case?
Thanks.

nevermind, i messed it up. sorry.
Can I ask what you messed up?
I had no troubles recompiling the kernel on 6.3.5 (to add in usbserial and cp210x modules). Can't figure out what's changed in 6.4.0, but "installing" the new kernel isn't taking effect (the boot changes in 6.4.0?).
And when compiling them as modules, I'm getting the same error as you.
What'd I miss??
Thanks!
The following steps worked for me eventually. I've only tried compiling modules, not replacing the entire kernel, so can't help you with that.
make oldconfig
make menuconfig
make prepare
make modules_prepare
make
make SUBDIRS=scripts/mod
make SUBDIRS=path/to/module modulesmake modules_install
depmod -a
