Description of problem:
As part of glibc testing for RHEL6, we run the src.rpm testuite too. On i686 and s390x, the box hangs during the execution of the testcase. Actually, the i686 box seems to reboot itself after a while. s390x box stops to respond.
I was tracking which testcase is causing this behavior, and it seems to be nptl/tst-eintr1.
Logs give almost no useful output, except for s390x, which spits this to the console:

Version-Release number of selected component (if applicable):
# rpm -q glibc
# uname -r
(the i686 versions are identical)
Steps to Reproduce:
1. install glibc src rpm
2. rpmbuild -bc /usr/src/redhat/SPECS/glibc.spec --target=`uname -m`
3. cd /usr/src/redhat/BUILD/glibc-2.12-2-gc4ccff1/build-s390x-linuxnptl
4. make -k check
5. waaaaait... until the nptl/tst-eintr1 testcase
The 'glibc' component is mostly a guess from me. Given the nature of the testcase, I can imagine it being a bug in anything from glibc (ld-linux), gcc/ld (badly built ld-linux), or kernel...
