It's true that each section about a particular build could have a
link to the page on the dashboard with all the details, that's
something to improve.

The way to find things out right now is to start with the main
link from the top of the email report, which shows all the builds
for this kernel revision:

  https://kernelci.org/build/arm64/branch/for-kernelci/kernel/arm64-fixes/

Then you can see the ones with errors, including the allmodconfig one:

  https://linux.kernelci.org/build/id/60f59321f76d8d0f141160be/

There's also a direct link to the logs, and then it takes a bit
of manual hunting.  The error mentioned here can be found in the
modules build log:

  https://storage.kernelci.org/arm64/for-kernelci/arm64-fixes/arm64/allmodconfig/gcc-8/logs/modules.log

I guess you could take a look at allmodconfig build logs from
linux-next now it's merged, to see if it's also there.

Hope that helps.

Best wishes,
