It caused bunch of "EMPTY CRPB" messages and potentially may cause premature requests completion, which could cause data corruption. For most cases it seems enough to just reread register to get proper value. To protect against worse cases - erase processed queue entries with impossible values and ignore them if problem still happen. |
