Hi Colin, Please take a look at the following patch https://lists.lttng.org/pipermail/lttng-dev/2017-March/026959.html
Could you report to us if it fixes your issue? Please note that s390 is not supported/tested by LTTng-modules. You probably encountered this bug since no syscalls tracepoints are getting defined on lttng-modules side. Please take a look at this git subtree [1] and the following readme [2] on how to generate it and add the headers for the S390 architecture if you wish to. Cheers [1] https://github.com/lttng/lttng-modules/tree/master/instrumentation/syscalls [2] https://github.com/lttng/lttng-modules/blob/master/instrumentation/syscalls/README -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1671063 Title: ubuntu_lttng_smoke_test failed on Yakkety s390x (zVM) Status in linux package in Ubuntu: In Progress Bug description: Two test cases failed on this arch: == lttng smoke test list kernel events == PASSED (lttng list --kernel) Error: Unable to list system calls: Not enough memory Error: Command error FAILED (lttng list --kernel --syscall) FAILED (lttng list --kernel --syscall more output expected) == lttng smoke test trace open/close system calls == ...
