The rest of the machine is its normal pretty snappy self. The lcnc lockup isn't acting like a busy loop, not lagging the rest of the machine a bit. The SSD isn't reporting its full size of 60G, but about 57G, filesystem reserve probably, and 29% used. But I see its not mounted with noatime either, probably should be?
Latency-test reports a worst case servo-thread jitter of 33 microsecs, no base-thread but 20 u-secs.
