Hi all,
after a long time after the merge of the s390x arch into the main koji
build-system we finally got the remaining infrastructure issue fixed
and we should be having the composes for F-27 and Rawhide available
regularly, see compose/Server/s390x/ or compose/Everything/s390x/
directory at [1] for F-27 and [2] for Rawhide. And there will be
official s390x composes for the F-27 GA testing, alongside all other
architectures.
Right now we see a segfault related to the transactional execution
(TE) when the installer boots the kernel, it has been reported as [3],
seems related to the lock elision in glibc. The TE bit is now visible in
guests under z/VM 6.4, earlier an LPAR was required to make use of the
TE feature. Using a one-off compose with special glibc build with the
lock elision disabled I was able go through the installation and got a
working system after the installation.
