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 Author: Ilia Mirkin <imir...@alum.mit.edu> Date: Tue Dec 16 13:55:38 2014 -0500 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. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=87361 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=74492 Fixes: fa8c9ac72fe ("drm/nv4c/mc: nv4x igp's have a different msi rearm register") Signed-off-by: Ilia Mirkin <imir...@alum.mit.edu> Signed-off-by: Ben Skeggs <bske...@redhat.com> Signed-off-by: Greg Kroah-Hartman <gre...@linuxfoundation.org> 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? -- Agustin -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
