2 months ago it could be an issue with the perf_event driver with your CPU. Could you please try this:
su
export PCM_NO_PERF=1
pcm -rClosed paulmenzel closed 1 month ago

READ : bytes read from main memory controller (in GBytes)
WRITE : bytes written to main memory controller (in GBytes)
IO : bytes read/written due to IO requests to memory controller (in GBytes); this may be an over estimate due to same-cache-line partial requests
