http://bugzilla.opensuse.org/show_bug.cgi?id=1163684 Bug ID: 1163684 Summary: Kernel oops in s390x tumbleweed Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: S/390-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: azouhr@opensuse.org QA Contact: qa-bugs@suse.de CC: mikef@suse.com, slindomansilla@suse.com Found By: --- Blocker: --- Since a while, the buildservice encounters a certain type of kernel oops, which often goes away when doing a restartbuild of the respective package. Since the php7:test package seems to encounter the issue more consistently, it seems a good candidate to reproduce the issue: osc rbl openSUSE:Factory:zSystems php7:test standard s390x PASS Leak 001: Incorrect 'if ();' optimization [ext/opcache/tests/leak_001.phpt] [ 1471.342879] Unable to handle kernel pointer dereference in virtual kernel address space [ 1483s] [ 1471.343112] Failing address: 000003d280000000 TEID: 000003d280000803 [ 1483s] [ 1471.343246] Fault in home space mode while using kernel ASCE.

Building the package on a SLES12 kernel did work without problems. The last time the package php7:test built successfully was 2020-02-04 10:24:13 669482aecc8852f512a26aa6d813bd41 7.4.2-1.4 72 3362 Since php7:test is quite late in the build tree, I guess that this problem was introduced with Kernel 5.5.1. -- You are receiving this mail because: You are on the CC list for the bug.
