Dear maintainer(s),

You recently added an autopkgtest, which is great. However, it fails on
riscv64. What's worse, it fails (among others) because it seems to hang
and eventually times out due to autopkgtest. Can you please investigate
the situation and fix it? I copied some of the output at the bottom of
this report.

Tests that time out (while normally running in much less time; e.g. < 2
minutes on amd64) are bad for our infrastructure.

More information about this bug and the reason for filing it can be
found on
