https://bugzilla.suse.com/show_bug.cgi?id=1227900 Bug ID: 1227900 Summary: Speculative Store Bypass disabled via prctl Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 URL: https://openqa.opensuse.org/tests/4344305/modules/jour nal_check/steps/9 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: mloviska@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: openQA Blocker: Yes Created attachment 876064 --> https://bugzilla.suse.com/attachment.cgi?id=876064&action=edit first boot log ## Observation During the firstboot of the image, journal log scan on Minimal-VM's cloud image[1] shows below errors/warnings that we have never noticed before on other images that the same test case is being executed. I cannot reproduce the issue on my local openQA running on an intel machine. This snippet comes from opensuse worker (openqaworker20) running AMD EPYC 7543 32-Core Processor.
