[Bug 1970076] Re: "User process fault: interruption code 0011 ilc:3" on SSH client/server upon Jammy upgrade

[Jeff White]

I can confirm that the issue may be in qemu in 22.04.  A "real" s390x
running 22.04 does not have this issue and the same installation image
does not have this issue running on Windows 11, qemu version 7.0.0.
