invalid or unsupported event: '{[snip]}'
Run 'perf list' for a list of valid events

 Usage: perf stat [<options>] [<command>]

    -e, --event <event>   event selector. use 'perf list' to list available events

The issue appears to be this event:

cpu/event=0xb7,umask=0x1/puhu

which has a duplicate u specifier.
