Excerpting from bug #253156 comment #6; two systemtap testsuite failures appear to be correctable with a kernel patch. The severity of this bug is low, but so appears to be the risk. > FAIL: backtrace of yyy_func4.return (3) > FAIL: print_stack of yyy_func4.return (1) To fix this issue, we need to introduce following kernel enhancement. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3661999a17b0397c7a93c200b280c55958ba3593;hp=965d747264c91ed206846d74ae09f757a36a373b
Frank, I've tried to reproduce the issue on: - systemtap version 0.6.2/0.131 built 2008-03-12 - kernel-2.6.18-92.1.6.el5 - kernel-2.6.18-97.el5 with the fix from upstream applied http://people.redhat.com/aarapov/kernel/ and no luck... or otherwise - _luck_. testsuite tests done almost sucessfully and absolutely identically on both kernels. # make installcheck [...] FAIL: buildok/rpc-all-probes.stp FAIL: buildok/signal-all-probes.stp [...] === systemtap Summary === # of expected passes 459 # of unexpected failures 2 # of unexpected successes 1 # of expected failures 170 # of unknown successes 1 # of known failures 5 # of untested testcases 19 # of unsupported tests 1 N.B. make check gave me exactly the same FAILs. Does it mean that failures magically disappear or somebody has something misconfigured? Did I miss something? // putting bz in NEEDINFO
Sorry, I made a mistake: bug #232489 comment #27 appears to include this patch already. *** This bug has been marked as a duplicate of 232489 ***
