I was unable to reproduce this bug using a kernel cross-built from tag
debian/4.19.146-1 in the repository
https://salsa.debian.org/kernel-team/linux.git on a Buster amd64 host or
a Stretch amd64 host. I used the config from the official kernel with
only CONFIG_LOCALVERSION and CONFIG_SYSTEM_TRUSTED_KEYS changed.

Is debian/4.19.146-1 the right tag for the kernel sources used by
linux-image-4.19.0-11-armmp 4.19.146-1? If so, why does this bug only
happen with the official package but not with one I built locally?

One thing that seems odd is that the package built from tag
debian/4.19.146-1 identifies itself as 4.19.87, not 4.19.146.
