Package: linux-perf-4.17 Version: 4.17.14-1 Severity: important Dear Maintainer,
fairly frequently, after recording perf data with perf record -F99 --call-graph dwarf [...] when I then immediately do perf report I get an error message saying failed to process sample 0x44098e [0x8]: failed to process type: 68 making the recorded data unusable (at least so far I found no way to use it). All I can do is record again, maybe with lower frequency, and hope that this time the problematic event does not happen... I have rebooted the machine since the last kernel upgrade, so the perf tool and the running kernel should match exactly.
