Hi Colin, what system is this on? The failing instruction should be a read of SPRG3:
│0x3fffb7f807c8 <__kernel_getcpu> mfspr r5,259 which should be fine to execute in userspace. There was a NUMA_BALANCING bug around that time where we'd end up mapping the vdso no execute, but I don't think Ubuntu is enabling that feature. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1673414 Title: sched_getcpu on ppc64le produces an illegal instruction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1673414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
