Comment 5 Marc Collin 2013-09-22 08:01:19 UTC
nouveau E[PBUS] [0000:01:00.0] MMIO write of 0x000401 fault
not nouveau E[PBUS] [0000:01:00.0] MMIO write of 0x000000 fault

so surely a nouveau driver problem
Comment 6 Lan Tianyu 2013-09-22 08:04:41 UTC
Yes, I think so too and so reassign the bug to correct category.
