It can easily be reproduced by: perf record -o - noploop | perf annotate that in my system shows: 0xd8 [0x28]: failed to process type: 9 Committer Testing: Before: $ perf record -o - stress -t 2 -c 2 | perf annotate --stdio stress: info: [11060] dispatching hogs: 2 cpu, 0 io, 0 vm, 0 hdd 0x4470 [0x28]: failed to process type: 9 $ stress: info: [11060] successful run completed in 2s $ After: $ perf record -o - stress -t 2 -c 2 | perf annotate --stdio stress: info: [11871] dispatching hogs: 2 cpu, 0 io, 0 vm, 0 hdd stress: info: [11871] successful run completed in 2s [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.000 MB - ] no symbols found in /usr/bin/stress, maybe install a debug package?
