Bug ID: 203647 Summary: Locking API testsuite fails "mixed read-lock/lock-write ABBA" rlock on kernels >=4.14.x Product: Platform Specific/Hardware Version: 2.5 Kernel Version: 5.1.3 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: PPC-64 Assignee: platform_ppc...@kernel-bugs.osdl.org Reporter: erhar...@mailbox.org Regression: No Created attachment 282831 --> https://bugzilla.kernel.org/attachment.cgi?id=282831&action=edit dmesg (5.1.3, G5 11,2) Probably this test fails on ppc64 since it is around. Kernel 4.9.x passes all tests, since it does not seem to contain "mixed read-lock/lock-write ABBA". Machine is a PowerMac G5 11,2 running Gentoo Linux ppc64, Big Endian, 4 KiB pagesize.
