perf-3.0 + 2.6.38
perf record -agR gives:
Can't find id 9's machine
Found 1 unknown events!
perf-3.0 + 2.6.32
perf record -ag
perf script
samples have bogus timestamps
perf-3.0 + 2.6.32
perf record -agR
perf script
error: Samples do not contain timestamps
perf-3.0 + any kernel
perf record -agT
perf script
is happy everywhere. Thanks!
