Comment 1 Alexandre Belloni 2023-08-10 15:24:53 UTC

Also happens with ptrace-Xabbrev.gen

Not seen for almost a year.

Comment 3 João Marcos Costa 2024-12-02 09:01:02 UTC

https://valkyrie.yoctoproject.org/#/builders/61/builds/492/steps/12/logs/stdio

Failed ptests:
{'strace': ['ptrace-Xraw.gen.test', 'ptrace-Xraw.gen']}

qemuarm64-ptest ubuntu2404-vk-arm2

These are ptrace-Xraw, likely related to ptrace-y-Xraw. Reopening.

I searched for logs in https://valkyrie.yocto.io/pub/non-release/20241129-87/testresults/ but there was no entry for "qemuarm64-ptest".

Comment 4 Randy MacLeod 2024-12-05 15:43:48 UTC

I'll get to this soonish.

Comment 5 Randy MacLeod 2026-01-08 16:27:36 UTC

Not seen in years.
