insmod ko: Invalid module format

[zener]

I just updated my system:

Code:

/etc/debian_version
buster/sid
root@rockpro64:/tmp# uname -a
Linux rockpro64 4.4.132-1075-rockchip-ayufan-ga83beded8524 #1 SMP Thu Jul 26 08:22:22 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux

However if I insmod a kernel module which have just been compiled using /usr/src/linux-headers-4.4.132-1075-rockchip-ayufan-ga83beded8524 I get:

Code:

insmod: ERROR: could not insert module xtrx_linux_pcie_drv/xtrx.ko: Invalid module format

root@rockpro64:/tmp# dmesg | tail -1
[98715.709490] xtrx: version magic '4.4.132 SMP mod_unload aarch64' should be '4.4.132-1075-rockchip-ayufan-ga83beded8524 SMP mod_unload aarch64'

How can I resolve this inconsistency?
