Message-ID<IFQNH-er5S-11@gated-at.bofh.it>
Package: autopkgtest
Version: 5.35
Severity: normal

I ran

followed by

> autopkgtest . --test-name=initrd-boot -- qemu /opt/chroots/autopkgtest-qemu.img

in a directory that is a checkout of https://salsa.debian.org/wouter/nbd.git

It installed the test dependencies, and then failed on:

which I did not expect...

Hi, this seems to be the same of:

https://bugs.launchpad.net/ubuntu/+source/autopkgtest/+bug/2056461

which turned out to be a kernel bug. If you want to verify that's
actually the case, I suggest running autopkgtest --debug and checking
that the timeout happens during a "copydown" operation.
