We are getting failures on qemu:
https://lava.ciplatform.org/scheduler/job/1377239
https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/jobs/12671190285
https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/pipelines/2253660286

Not sure if it is real problem or just something wrong with test
configuration. 6.18.4 had similar problem iirc.

I'm cc-ing our testing people, maybe they'll help.

Best regards,
