Also seen here on riscv64 with 1.4.2-3:

https://ci.debian.net/packages/g/golang-github-containerd-accelerated-container-image/unstable/riscv64/72219240/#L24964

And here on amd64:

https://ci.debian.net/packages/g/golang-github-containerd-accelerated-container-image/unstable/amd64/72351360/#L25659

Another amd64 failure:

https://ci.debian.net/packages/g/golang-github-containerd-accelerated-container-image/unstable/amd64/73900962/#L25476

And another one:

https://ci.debian.net/packages/g/golang-github-containerd-accelerated-container-image/unstable/amd64/73900963/#L25737

Exactly which tests fail appears random in each log.
