I've tried to reproduce this since yesterday, but couldn't until now:
2>&1 made all the difference, took less than a minute.

Different repo, different machine, but also running Tumbleweed 5.14.1-1-default, git 2.33.0

while [ "`git --git-dir=$PWD/in/linux/.git ls-remote origin 2>&1 | tee failed.out | sha1sum`" = "7fa299e589bacdc908395730beff542b0fc684eb -" ]; do echo -n .; done ..........

failed.out has multiple lines like this:

--8<-- 4e77f7f1261f65cff06918bc5e66d02a418fc842 refs/tags/v3.10.18^{} f7b8df0cc81cf82a4ac6834225bddbe46a340455a4a5d52f29d08d923ce8d232b0b497da674dd2c refs/tags/v3.18 b2776bf7149bddd1f4161f14f79520f17fc1d71d refs/tags/v3.18^{} --8<--

Running the same on Archlinux (5.13.13-arch1-1, 2.33.0) doesn't show the problem. This may well turn out not to be git, but a kernel issue.

@Eike: I think at this point you should try to downgrade and see whether that makes any difference
