I suspect this test is giving me intermittent hangs. I've seen the hangs
in different machines, but when they're lightly loaded the
hang happens more frequently.
To reproduce:
$ ./configure --target-list=s390x-softmmu
$ make clean && make
$ for i in $(seq 0 150); do echo $i && make -j check-qtest || break; done
It usually ends up hanging before 50 runs. When the hang happens, I see
two qemu-system-s390x processes with:
-serial file:/tmp/migration-test-0FZErQ/dest_serial
as an argument, among others. That means the migration test is the
one hanging, correct?
Attaching with gdb just shows the TCG thread waiting for work
in qemu_tcg_rr_wait_io_event.
Can anyone reproduce this? Otherwise, let me know what other info
I could provide.
Thanks,
Emilio
