Lemme add a whole bunch of relevant ppl to Cc.

So I'm seeing this with an allmodconfig build too:

depmod: ERROR: Cycle detected: 8250 -> 8250_base -> 8250
depmod: ERROR: Found 2 modules in dependency cycles!
make[6]: *** [scripts/Makefile.modinst:132: depmod] Error 1
make[5]: *** [Makefile:1917: modules_install] Error 2
make[4]: *** [Makefile:2140: run-command] Error 2
make[3]: *** [debian/rules:66: binary-image] Error 2
dpkg-buildpackage: error: make -f debian/rules binary subprocess returned exit status 2
make[2]: *** [scripts/Makefile.package:126: bindeb-pkg] Error 2
make[1]: *** [/home/amd/kernel/linux/Makefile:1643: bindeb-pkg] Error 2
make: *** [Makefile:248: __sub-make] Error 2

That's 6.17.7
