Ok this failure is quite something.
1. in stdout/stderr
Test requirement not met in function igt_device_set_master, file
../lib/igt_device.c:61:
Test requirement: __igt_device_set_master(fd) == 0
Can't become DRM master, please check if no other DRM client is running.
command pid dev master a uid magic
kms_cursor_crc 6870 0 y y 0 0
kms_cursor_crc 6870 0 n y 0 0
perf_pmu 6999 0 n y 0 0
perf_pmu 6999 0 n y 0 0
Received signal SIGQUIT.
This means that we have some other IGT test alive that should not have been
there. Runner should have killed them or failed earlier if they are not
killable. I have to double-check child handling in igt_runner.
2. run.log told us that we got EBADF
Failed to stop a watchdog: Bad file descriptor
Failed to stop a watchdog: Bad file descriptor
Timestamp 1562355594
/tmp/jenkins2496193922192201218.sh: line 118: 6978 Terminated
stdbuf -o0 dmesg -rw > "$LOGDIR/$RUN/dmesg.log" 2>&1 (wd: /opt/igt)
So the runner was terminating just fine and even tried to stop watchdog (now we
can tell because logging added in comment #36) but it failed. I guess we need
to start logging fds while initializing and then when closing to see what is
going on.
Anyway, seems like the system was in a completely broken state (hanging
processes, defunct watchdogs). Let's see whether we see similar issues with
other failures.
