This is load related. I can run:
retry.py --timeout 600 -n 500 -c -- \
env QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 \
QTEST_QEMU_IMG=qemu-img ./tests/cdrom-test \
-m=quick -p /x86_64/cdrom/boot/isapc
and then all 500 run fine. If I do the same while running a make check
check-tcg -j9 in another build directory it hangs within 20 odd
attempts.
Can anyone else reproduce this?
