I've been consistently observing test failures in systemtap.syscall/tp_syscall.exp test files on  kernel 4.16.16 x86_64 on Fedora 27:

I've attached the full systemtap.log for that test file.
Comment 1 Frank Ch. Eigler 2018-11-13 15:58:26 UTC 
Git systemtap with current 4.18+ stream kernels score much better on the syscall tests.  Shall we close this as CURRENTRELEASE?
Comment 2 agentzh 2018-11-13 17:41:54 UTC 
Hi Frank,

Haven't got a chance to rerun the whole test suite against the latest git version. But feel free to close it now. I can always reopen it when I see these again :)
Comment 3 Frank Ch. Eigler 2018-11-13 18:22:45 UTC 
current version appears to work fine
