It is likely a misbackport of the upstream commit. i opened https://bugzilla.suse.com/show_bug.cgi?id=1119962 i used Leap 15 and opensuse as target as Cat "SUSE Linux Enterprise Server" is no longer available to public.

Is an opensuse bugtracker entry really required or is this something to discuss upstream?

Dear Michal, the reproducer is pretty easy. Start two VMs from the same clone using qemu/kvm and enable ksm + maximaize scan pages to trigger it fast. That's it.

[opensuse-kernel] KMPs fail to build
by Manfred Hollstein 07 Dec '18

07 Dec '18

Hi there, since a few days, I see the following in my buildlog: error: File not found: /home/abuild/rpmbuild/BUILDROOT/broadcom-wl-6.30.223.271-12.16.x86_64/lib/modules/%2-default RPM build errors: line 64: Possible unexpanded macro in: Version: 6.30.223.271_k%2 line 64: Possible unexpanded macro in: Provides: broadcom-wl-kmp = 6.30.223.271_k%2 File not found: /home/abuild/rpmbuild/BUILDROOT/broadcom-wl-6.30.223.271-12.16.x86_64/lib/modules/%2-default As you can see, the kernel version doesn't get expanded properly. This is from building my own KMP for the home:manfred-h/broadcom-wl wireless driver, but it appears that all KMPs currently fail with a very similar message; all but one packages from Kernel:stable:KMP show the same behaviour. Has anything changed in the KMP environment in OBS? FWIW, the same package used to build up until kernel version 4.19.6-2 TIA, cheers. l8er manfred
