FTR, I noticed that linux 4.9.82-1+deb9u3~bpo8+1 failed on buildd's and still not available on i386 and amd64. Probably, something can/should be done about that? https://buildd.debian.org/status/package.php?p=linux&suite=jessie-backports Dependency installability problem for linux on amd64: linux build-depends on missing: - gcc-4.9:amd64 (>= 4.9.2-10+deb7u1)
