Comment 1 Petr Vorel 2023-09-01 10:43:15 UTC

It's a new test added in [1] (last working build uses the same kernel).

I have no idea if it's a test bug or kernel bug or openQA issue (Debian with kernel 6.4.11 works well, Tubleweed currently have kernel 6.4.12-1).

I'm away for 2 weeks, thus just reported upstream [2] and Cc related developers.

Comment 2 Petr Vorel 2023-09-01 12:38:45 UTC

It's probably test a bug due missing swap [1].

I suppose bug should be set as invalid (not a kernel bug, but LTP regression).

Comment 3 Richard Palethorpe 2023-11-15 08:42:44 UTC

The fix was applied and it appears the test now refuses to run (as it should):
