Thanks for the bug report.

So some kind of timeout …

Whatever the reason is, it's not the update from 0.800 to 0.801, as
the whole diff (modulo versions numbers etc.) is:

Looking at https://ci.debian.net/packages/libi/libio-async-perl/testing/ppc64el/
I notice that the tests for 0.800-2 also failed. Not sure if this
good or bad :)

Ah, in 0.800-2 we have:

libio-async-perl (0.800-2) unstable; urgency=medium

  * Don't skip any tests, as Test::Future::IO::Impl is in Debian.
  * Add test dependency on libfuture-io-perl.

and t/70future-io.t was skipped in 8.800-1.


So t/70future-io.t fails consistently since it is run (0.800-2 and
0.801-1). But only on ppc64el.


Cheers,
gregor
