I am using a Blackbird Desktop System with an IBM Power9 v2 (= stepping DD2.3) 8-core CPU as testing infrastructure for open source projects (since Jan, 2020).
Instable hardware watchpoints in stepping DD2.2 (erratum #1: DAWR [Data Access Watchpoint Register] feature is disabled on DD2.2) was the main reason for me to wait for DD2.3 to have reliable low-level debugging available.
