Hi Vagrant,

Vagrant Cascadian <vagrant <at> debian.org> skribis:

Did you try attaching strace or gdb to the faulty test to see what’s
going on?

It may be that this test depends on the availability of special hardware
or something like that, in which case we should arrange to skip just
this test.

Thanks for looking into it!
