Hi,
I was thinking about building a kernel with patch mentioned in
http://bugs.debian.org/758460
http://cgit.freedesktop.org/~darktama/nouveau/commit/?id=b7387454bda64a16350fabee4d81bec3b8de8fa2
applied, but I then noticed that it is already in jessie's kernel.
Searching kernel changelogs, I found this in
https://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.18.4
commit 715f7c8214c7822833af757109022006c3f01d6a

drm/nv4c/mc: disable msi
commit 4761703bd04bbdf56396d264903cc5a1fdcb3c01 upstream.
Several users have, over time, reported issues with MSI on these IGPs.
They're old, rarely available, and MSI doesn't provide such huge
advantages on them. Just disable.

register")

also in https://www.kernel.org/pub/linux/kernel/v3.0/ChangeLog-3.14.30 (LTS?)
Now it is clear why setting NvMSI=0 did not make any difference in the box
with the GeForce 6150SE where I hit the bug (Did not try with noaccel).
Martin-Éric, has jessie's kernel fixed the problem in your box?
