I build vanilla kernel with debian config, and here's the result. (images are under arch/arm/boot/) linux_4.10.7 with debian 4.10.7 config -rwxr-xr-x 1 rosh rosh 5757504 Aug 20 06:40 Image -rwxr-xr-x 1 rosh rosh 2012496 Aug 20 06:40 zImage linux_4.11.6 with debian 4.11.6 config -rwxr-xr-x 1 rosh rosh 8763712 Aug 20 07:03 Image -rwxr-xr-x 1 rosh rosh 2064576 Aug 20 07:03 zImage linux_4.11.6 with debian 4.10.7 config -rwxr-xr-x 1 rosh rosh 5891216 Aug 20 07:43 Image -rwxr-xr-x 1 rosh rosh 2049216 Aug 20 07:43 zImage linux_4.10.7 with debian 4.11.6 config -rwxr-xr-x 1 rosh rosh 5811408 Aug 20 07:56 Image -rwxr-xr-x 1 rosh rosh 2032704 Aug 20 07:56 zImage So it seems the problem is pointing to config changes since 4.11.
