Most of the errors look to be debuginfo problems with 1 build-id problem. >> FAIL: systemtap.examples/general/badname build >> FAIL: systemtap.examples/general/badname run Hmm, it looks like the test should be a bit smarter and not try to run a script if it fails to build. Anyway, this one fails with errors like: semantic error: failed to retrieve location attribute for local 'child' (dieoffset: 0xf3c95c): identifier '$child' at badname.stp:16:7 source: if ($child->d_inode || $dir->i_flags & 16) next This looks like a debuginfo problem. Can you show me the output of: # stap -L 'kernel.function("may_create@fs/namei.c")' >> FAIL: systemtap.examples/io/iostat-scsi run This one failed with: ERROR: Build-id mismatch: "sd_mod" vs. "sd_mod.ko" byte 0 (0xc1 vs 0x00) rc 0 -14 which means that stap doesn't think your debuginfo and the actual module match. Other stap folk can probably expound more here. >> FAIL: systemtap.examples/network/netdev build >> FAIL: systemtap.examples/network/netdev run This one failed with: semantic error: failed to retrieve location attribute for local 'dev' (dieoffset: 0x2daa6f2): identifier '$dev' at /usr/local/share/systemtap/tapset/networking.stp:159:29 source: dev_name = get_netdev_name($dev) I'd bet this one is a debuginfo problem.
