I realise that the the values PGRAPH complains about are indeed wrong, the question is how did they end up corrupted like this? I'm assuming since this is a SIFC transfer and method 0x860 is SIFC_DATA that the PFIFO errors are a symptom of an earlier problem, the same thing that caused the PGRAPH errors. This is a fairly recent nouveau kernel, a few commits behind the latest one.
Any ideas how to pursue this problem?
