I reran three or four times the autopkgtest on arm64 on my host
with no issues.  The rerun on official CI also went fine in a
very reasonable time[1].  CI history of jellyfish[2] reveals two
occurrences of this issue lately, and the run from 2023-10-09
happens to have a mismatching run time reported in the test
log[3].  There is one much older occurrence from last year, on
2022-10-02, but no log associated given its age.  The hundreds
of other runs were not affected by this issue.  I'm tempted to
put that on a momentary hardware glitch at this point.

Have a nice evening,  :)
