Comment 2 Randy MacLeod 2024-07-25 14:47:07 UTC 
An intermittent bug that is in an async case so likely timing related.

If it happens again, disable the test.

Not the same taskgroup, though. This was test_taskgroup_04.

Failed ptests:
{'python3': ['python3']}

there is no 'test_taskgroup_23' in the list, but according to the logs:

Hasn't happened on the new YP AB.
Comment 7 João Marcos Costa 2026-03-09 10:14:22 UTC 
Happened again:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/61/builds/3190/steps/13/logs/stdio

qemuarm64-ptest ubuntu2504-vk-arm1

Reopening, just in case.
Comment 8 Randy MacLeod 2026-03-12 14:55:49 UTC 
Patch out and report to upstream, mabye?
Comment 9 Randy MacLeod 2026-03-19 15:05:01 UTC 
Either increate timeout or skip test if that doesn't make sense.
