Control: retitle -1 nouveau: NV4E acceleration corruption when DMA above 31-bit (2 Gig barrier)
Control: forwarded -1 https://bugs.freedesktop.org/show_bug.cgi?id=46557
For those who don't want to read the whole bug log: this bug is about
severe display corruption for those cursed with an Nvidia NV4E
(GeForce 6100/6150) graphics chip under two conditions:
- The machine has more than 2 Gigabyte RAM.
- A 64-bit kernel is used.
In this case, the machine is unusable with nouveau unless memory is
restricted to 2 Gigabyte (mem=2G) or acceleration is disabled
(nouveau.noaccel=1). For details, see the upstream bug on
https://bugs.freedesktop.org/show_bug.cgi?id=46557.
Cheers,
Sven
