Docker Buildx hangs on Webpack

[fmorett]

Issue is a bit random

This issue sadly is not really reproducable.

Sometimes with all caches cleared it works but sometimes not. (about 10% of the time it hangs til a full restart)

Buildx output looks suspicous:

So aparently after just 10 seconds the webpack task has already taken 91000 seconds???

(The build api task uses webpack under the hood)

Further information

This issue first appeared after upgrading docker and my linux distro (was 20.10 ubuntu now is 21.10 ubuntu). Also cgroups 2 are new which has introduced some problems in old docker versions.

@Fibs7000 Would need a repro to be able to test on our side (Dockerfile, build command used and buildx/buildkit version). Thanks.
