http://bugzilla.opensuse.org/show_bug.cgi?id=1079747 Bug ID: 1079747 Summary: Kernel 4.15 seems often to stall the OBS workers Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: dimstar@opensuse.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Since the upgrade to Kernel 4.15, I see a much increased number of 'stalled' OBS workers. The stall happens in various packages, most prominently, llvm5, ceph, libreoffice and java-9-openjdk. Most of the time, they are 'fine' after several attempts. There seems to be one package reliably reproducing it: tar on i586 https://build.opensuse.org/package/live_build_log/openSUSE:Factory/tar/stand... I'm CCing Adrian (OBS Admin) here, as he will likely be the only person that can provide traces from the VM, at the time this happens. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1079747 http://bugzilla.opensuse.org/show_bug.cgi?id=1079747#c3 Adrian Schröter changed: What |Removed |Added ---------------------------------------------------------------------------- Flags|needinfo?(adrian@suse.com) | --- Comment #3 from Adrian Schröter --- build.opensuse.org is ready for handling some sysrq now.. You can use the latest osc (unstable build) from devel:tools:scm project and run eg: osc sendsysrq $project $package $repo $arch 9 osc sendsysrq $project $package $repo $arch t osc sendsysrq $project $package $repo $arch w to trigger sysrequests (note, only a subset is allowed via a whitelist, tell if you miss one). Alternative is to do it via the api, eg: osc api -X POST '/build/science:unstable?cmd=sendsysrq&arch=x86_64&sysrq=9&repository=openSUSE_Tumbleweed&package=FreeCAD' or use your favourite tool to speak HTTP... /me hopes that I am not the only one anymore who can debug guest kernels :) -- You are receiving this mail because: You are on the CC list for the bug.
