Priority: medium
Bug ID: 66696
Assignee: nouveau at lists.freedesktop.org
Summary: Nouveau does DMA to/from unexpected address
QA Contact: xorg-team at lists.x.org
Severity: major
Classification: Unclassified
OS: Linux (All)
Reporter: stijn+bugs at linux-ipv6.be
Hardware: x86-64 (AMD64)
Status: NEW
Version: unspecified
Component: Driver/nouveau
Product: xorg
It appears that on my GeForce 7600 GS (G73), nouveau is doing DMA to/from
unexpected addresses. This gives a lot of warnings, and eventually a system
freeze. This is similar to https://bugs.freedesktop.org/show_bug.cgi?id=27063 /
https://bugzilla.redhat.com/show_bug.cgi?id=561267. This was fixed for nv50 in
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4eb3033c72099fab3536ed8ac54a5dc99f0832d7
but with the G73 I am seeing this problem in a 3.10 kernel.
