Source: linux Version: 4.14.13-1~bpo9+1 Severity: normal X-Debbugs-CC: backpo...@vger.kernel.org
It seems like the current kernel in stretch backporst and in buster has problems when compiling external modules against it. This worked fine in the past. Also works fine when compiling against a manually compiled 4.14 Linux kernel. So it seems to be a Debian specific regression. Here are some examples $ curl https://mirror2.openwrt.org/sources/backports-2017-11-01.tar.xz|tar xvJ $ make -C backports-2017-11-01 defconfig-ath9k $ make -C backports-2017-11-01 make: Entering directory '/usr/src/backports-2017-11-01' make[5]: 'conf' is up to date. # # configuration written to .config # Building backport-include/backport/autoconf.h ... done.
