Subject: Re: selftest: rtctest.c:290:alarm_wkalm_set:Expected -1 (-1) != rc
(-1) : Test terminated by assertion

This honestly looks like an infrastructure issue. How loaded are your
workers when running this test?
Also, I'm not sure how good is the rtc emulation in qemu (which is a
good part of what is being tested here).
