perf cpu events visible but not accessible in v6.6

I just installed the latest build (v6.6) (Linux BeagleV 6.9.12-20241117+).
While “perf list” works fine and lists all -supposedly- available events to count. When I ask for a specific counter (e.g. perf stat -e dtlb_miss /bin/ls) I get an error:

Unable to find event on a PMU of ‘dtlb_miss’
event syntax error: ‘dtlb_miss’
___ unknown term ‘event’ for pmu ‘cpu’

What I am doing wrong? Any help is appreciated.
