Comment 3 for bug 1913188

This testcase hasn't been changed in several months, so we can discard any recent testcase change causing the timeout.

However, looking at the logs for focal/linux-hwe-5.8 runs on arm64 there are some interesting data.

The last time the testcase was successful was with version 5.8.0-36.40~20.04.1:
https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-focal/focal/arm64/l/linux-hwe-5.8/20210108_133824_09617@/log.gz

Looking at the timestamps the test took a little bit over 19 min to finish.

Starting from version 5.8.0-37.42~20.04.1 it stated to fail:
https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-focal/focal/arm64/l/linux-hwe-5.8/20210113_031753_cd06b@/log.gz

The timeout reached was 1200 sec, i.e. 20 min.

This test has been running for a little under the timeout limit for the slower architectures, and at least for hwe-5.8 the changes introduced after -36 could not explain any change on the execution time of this testcase.

Therefore, I believe these failures have been caused by variations on the test systems and the testcase timeout should be adapted for expected longer runs.
