bug#48282: CI fails to build opencv on x86-64

Hi,

It looks like the build farm fails to build the opencv package on
x86-64. The build log (see [1] or [2]) indicates that the build
"timed out after 3600 seconds of silence" in the test phase, more
precisely in the 'opencv_test_aruco' test.

What is strange is that on my machine the build succeeds and this
'opencv_test_aruco' test takes less than 1 second.

Does someone see the test phase getting stuck when building opencv
locally?

Are you using Intel or AMD?

I ask because of this upstream bug report about ArUco not working on AMD
processors:

https://github.com/opencv/opencv_contrib/issues/2736

The build farm is AMD.

The machine I used to build opencv (successfully) also has an AMD
processor (AMD Ryzen 9 5950X).

I saw some reports of success with Ryzen chips; maybe it's a problem
with AMD Epyc, which will be more typical for build farms and
high-performance workstations.

It looks like this build failure doesn't happen anymore now.
Closing.
