Given that the last change didn't actually change any actual code,
this is odd. The output looks truncated.

Looking at the host (lfedora1) there seems to be something wrong.
dmesg contains a large number of the following messages:

The last few builds on lfedora1 also took way longer than usual.
https://builder.wildebeest.org/buildbot/#/builders/10
It used to take 30~40 minutes, but now it takes 3~4 hours...

I wonder if something is wrong with the s390x build host.

Thanks,

Mark
