...to write to VGA RAM. Nouveau uses this memory for different purposes, so if we are unlucky, it causes mysterious memory corruptions. For me, booting with nv_printk debug levels set to 5 was enough to trigger it. It manifested as long stream of: "trapped write at ... on channel 0x0001fea0 BAR/PFIFO_WRITE/IN reason: DMAOBJ_LIMIT / PT_NOT_PRESENT / PAGE_SYSTEM_ONLY / PAGE_NOT_PRESENT" which eventually lead to complete hang. Disabling access to VGA memory (through 0x54 PCI config space register) is enough to fix it, but it breaks copying screen data between old and new console (because old data...

The vblank on nvc0 was not working correctly and would freeze X, I managed to track it down and fix it with some help from m.b.lankhorst, see https://bugs.freedesktop.org/show_bug.cgi?id=56692 for details. -------------- next part -------------- An HTML attachment was scrubbed...

Hello List, I am trying to solve bug 58556 [1], but I will need some help as I don't understand all that is going on. The system is composed of an NV96 (9600 GT) and an NVAC (9400 M) card; acceleration is disabled, otherwise the system hangs at boot after initialising the NV96 card. The problem consist of a complete garbage screen in console mode, and a one-third gabage screen in GUI.
