git unreliable on sparc and 8.2

Hi,

GitHub is retiring its svn gateway, so I have to bite the bullet and use
git. I already use git with 9.3 on my SS4 as well as on 64bit on my
Netra... so quite some stuff to compile, but it works.
In the past years, I failed to compile git-base, but now, even on 8.2 it
compiled and installed. However, it appears to be unreliable.

I cloned a small repository, but if I clone some bigger stuff, I get:

bash-5.2$ git clone https://github.com/gnustep/libs-base
Cloning into 'libs-base'...
Could not open /dev/crypto: Device not configured
remote: Enumerating objects: 103223, done.
remote: Counting objects: 100% (1145/1145), done.
remote: Compressing objects: 100% (501/501), done.
error: RPC failed; curl 92 HTTP/2 stream 0 was not closed cleanly:

fetch-pack: unexpected disconnect while reading sideband packets
fatal: early EOF
fatal: fetch-pack: invalid index-pack output

I retry:
bash-5.2$ git clone https://github.com/gnustep/libs-base
Cloning into 'libs-base'...
Could not open /dev/crypto: Device not configured
remote: Enumerating objects: 103223, done.

fatal: fetch-pack: invalid index-pack output

it dies in another place... what is going on here? This is a SS10
dual-proc which is quite reliable! No messages in dmesg upon failures.

I keep trying and trying... I got one repository through eventually, but
libs-base just continues failing randomly,
