Dear maintainer(s),



                       pass            fail
gcc-11                 from testing    11.3.0-6

autopkgtest [21:13:57]: test kbuild

With a recent upload of gcc-11 the autopkgtest of linux fails in testing when that autopkgtest is run with the binary packages of gcc-11 from unstable. It passes when run with only packages from testing (it also fails in testing). In tabular form: Currently this regression is blocking the migration of gcc-11 to testing [1]. Of course, gcc-11 shouldn't just break your autopkgtest (or even worse, your package), but it seems to me that the test "only" fails on "Unexpected warning" and your package needs to update to the new situation. If this is a real problem in your package (and not only in your autopkgtest), the right binary package(s) from gcc-11 should really add a versioned Breaks on the unfixed version of (one of your) package(s). Note: the Breaks is nice even if the issue is only in the autopkgtest as it helps the migration software to figure out the right versions to combine in the tests. echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\ echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it.";
