Hi @davidhildenbrand, I'm on the same team as @nam121 and I've been
looking at this issue as well.
I think this is the same issue as: https://github.com/multiarch/qemu-
user-static/issues/129
I've been running an s390x docker image on a master build (with latest
s390x commit from Apr 23) of user
>From looking at the in_asm logs, it looks like that instruction starting
with 0xebde is executed once with no problem but the second time its
changed to 0x.
... # First Time
IN:
0x40126d6880: ebde f000 ec51 tmy -0x14000(%r15), 0xde
0x40126d6886: e3e0 f008 0024 stg
C code (s390x specific)
that reproduces the issue and can try to add it as a unit test.
