it works for me after updating F34 with this update the following test didn't report fail.

# git clone https://gitlab.com/cki-project/kernel-tests.git
# cd kernel-tests/distribution/ltp/openposix_testsuite
# dnf install -y git automake autoconf flex bison rsyslog util-linux rpm-build kernel-headers bc time kernel-devel libaio-devel libcap-devel strace gcc bzip2 numactl
# bash runtest.sh 
# cat failed_list
#

Before the update pthread_cond_destroy_2-1 would show as failed test.
