The message "Failed to allocate Tx DevX UAR (BF)" is diagnostic, not error. We lowered the log level for this to DEBUG in 21.02. If the further UAR all= ocation with NC mapping succeeds - there is no known issues about PMD opera= ting. (if both BF/NC fail - no device probing happens, as we saw). Hence - just ignore the diagnostic message or use 21.05 or apply the commit= " net/mlx5: fix UAR allocation diagnostics messages".
