failed to solve: rpc error: code = Unknown desc = executor failed running [/bin/sh -c go get -d -v ./...]: buildkit-runc did not terminate successfully

I do not get a any error on amd64 on golang official container but when i try to build multi platform with docker buildx, go get command has a error on arm and arm64.
So i try golang:alpine it gets a same error, I change kernel version and get same result.

Currently to temporarily, I create a alpine container and install go and git with package manager (apk) and replace FROM golang with my container. Now it is work.

/ # go version

A better place to report this may be the docker buildx issue tracker. Since docker buildx is an experimental feature and it seems to be initiating the go get command, they may have a clear understanding of what is happening. Closing this issue. Please comment if you disagree or if I have misunderstood.
