I skimmed over build logs of OBS Kernel:openSUSE-15.2, but couldn't find such a warning. -- You are receiving this mail because: You are on the CC list for the bug.

https://bugzilla.suse.com/show_bug.cgi?id=1185650 https://bugzilla.suse.com/show_bug.cgi?id=1185650#c3 --- Comment #3 from Michal Suchanek --- And it was introduced by this: commit 6ffe9923f2350c19b95a2c9ebf1b4f5f275986f2 Author: Will Deacon Date: Mon Aug 22 11:58:36 2016 +0100 arm64: errata: Pass --fix-cortex-a53-843419 to ld if workaround enabled Cortex-A53 erratum 843419 is worked around by the linker, although it is a configure-time option to GCC as to whether ld is actually asked to apply the workaround or not. This patch ensures that we pass --fix-cortex-a53-843419 to the linker when both CONFIG_ARM64_ERRATUM_843419=y and the linker supports the option. Acked-by: Ard Biesheuvel Signed-off-by: Will Deacon meaning that even if you select the erratum workaround it is not applied unless the linker has the option. The CPU architecture family affected is A53 which we certainly do support. The description is "Cortex-A53: 843419: A load or store might access an incorrect address" which may very well be behind random crashes of ARM builders in OBS. The IP revision is specified as "Cortex-A53 parts up to r0p4" and I have no idea how that maps to silicon revisions of actual CPUs. Also this probably needs to be enabled for userspace as well for the mitigation to work. -- You are receiving this mail because: You are on the CC list for the bug.
