Bug#1078424: nvidia-cuda-samples: autopkgtest needs update for new version of linux

[Paul Gevers]

Source: nvidia-cuda-samples
Version: 12.2~dfsg-1
Severity: serious
Tags: sid trixie
User: debian-ci at lists.debian.org
Usertags: needs-update
Control: affects -1 src:linux

Dear maintainer(s),

With a recent upload of linux the autopkgtest of nvidia-cuda-samples 
fails in testing when that autopkgtest is run with the binary packages 
of linux from unstable. It passes when run with only packages from 
testing. In tabular form:

                        pass            fail
linux                  from testing    6.10.3-1
nvidia-cuda-samples    from testing    12.2~dfsg-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of linux to testing 
[1]. Of course, linux shouldn't just break your autopkgtest (or even 
worse, your package), but linux is too much at the core of our 
infrastructure that we want to wait for updates of packages like 
nvidia-cuda-samples in contrib that seem to need too often be in 
lockstep. Is it possible to make the autopkgtest skip the test 
(restriction skipable with exit code 77) if a too new kernel is 
installed? Such that you can still see the difference between PASS and 
NEUTRAL for linux kernels and hence not blocking src:linux, while at the 
same time still have it failing on other regressions and thus blocking 
those from migrating?
