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/1267119... https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/pipelines/22...
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, Pavel
