https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #34 from Andreas Loew <awl1 at gmx.net> --- Bad news once again... I applied the following single-line patch to a stock 3.12.4 kernel in order to switch to the NV50 fence: diff -Nrpu linux-3.12.4.orig/drivers/gpu/drm/nouveau/nouveau_drm.c linux-3.12.4/drivers/gpu/drm/nouveau/nouveau_drm.c ---

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #31 from Ilia Mirkin <imirkin at alum.mit.edu> --- You really need to figure out how to do things inside the git tree and not do some sort of crazy export. That will speed things up by an order of magnitude. To get the list of nouveau changes between 3.4 and 3.5: git log v3.4..v3.5 -- drivers/gpu/drm/nouveau To do a bisect

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #28 from Andreas Loew <awl1 at gmx.net> --- This gets really interesting now: Oracle public yum "playground" 3.6.11-3.6.y.20121225.ol6 (should be stock kernel 3.6.11) does NOT show any hangs, but DOES INDEED ALREADY show the graphics corruption issue FOR ME (although it was thought by the original posters here that it

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #27 from Andreas Loew <awl1 at gmx.net> --- Hmm - bad news once again: I have now compiled and tested a 3.6.kernel to match the commit immediately before the "mega commit", i.e. the kernel tarball has been produced by the following command: $ git archive --format=tar

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #79 from Andreas Loew <awl1 at gmx.net> --- You're welcome! :-) I did do this in my very own interest, because the OL6/RHEL6 install on my main work laptop all of a sudden had this distortion issue when RHEL updated the drm/nouveau module to an affected codebase in RHEL 6.5, so I definitely needed a solution for this (other

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #22 from Andreas Loew <awl1 at gmx.net> --- Hello Ilia, regarding (a) and (b): I am just waiting for a rpmbuild of an OL6 version of 3.13-rc3 to finish and will report back on my findings and include a dmesg output from that version. Regarding (c): Would'nt it make more sense than starting with 3.6 release and 3.7 release

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #71 from Andreas Loew <awl1 at gmx.net> --- Hello Ilia, hmm - you just caught me with the update five minutes after I had started the rpmbuild with the previous version... ;-) Unfortunately, while I could make the first patch apply to a current RHEL kernel source with only one change (core/engine/device.c ->

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #19 from Andreas Loew <awl1 at gmx.net> --- Hello, I would like to join discussions in this bug, as I have found myself affected after the recent update from Red Hat Enterprise Linux/Oracle Linux 6.4 (stock RHEL kernel 2.6.32-358.23.2) to RHEL/OL 6.5 (RHEL kernel 2.6.32-431). My graphics card is NVidia Quadro NVS 130M: BOOT0

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #29 from Andreas Loew <awl1 at gmx.net> --- OK, finally I have some more encouraging news: It now looks like the issue indeed started much earlier than initially thought, namely already between the 3.4 and 3.5 kernel series!!! Results from my testing with stock kernels obtained from kernel.org (I've never ever before

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #30 from Andreas Loew <awl1 at gmx.net> --- In addition, one more request to all the other people who raised this issue here and/or have also seen it before myself: Can you confirm that for you, the issue indeed also already started after the 3.4 series like it does for me, i.e. you never tried a 3.5.x or 3.6.x kernels? Thanks

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #35 from Andreas Loew <awl1 at gmx.net> --- Follow-up question note that I am digging deeper into git... ;-) >From the commits in the v3.4..v3.5 range, only two of them: 9bd0c15fcfb42f6245447c53347d65ad9e72080b (dated Jun 26, 2012) and e9bf5f36b09f8ec6c168ef58ee7d4890545ede1c (dated Jun 27) when looking at the global

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #77 from Andreas Loew <awl1 at gmx.net> --- Sorry that it took me longer to get back here - I needed an additional rpmbuild run due to running out of disk space for my first attempt... But I can give an all clear signal - at least for my machine, AFAIK, everything seems to be fine: Kernel command line: ro

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #43 from Andreas Loew <awl1 at gmx.net> --- Hello again, so it looks like I have now tracked the issue down. The "offending" commit seems to be: 4c193d254ee94da02857b9670e815b1765a9579b (the first commit which showed the issue - I tried for more than half an hour with its direct predecessor

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #45 from Andreas Loew <awl1 at gmx.net> --- Hmm... While my card definitely is not at all defective (it works the exact same way it always has), I indeed also have some issues that make it impossible for me to still use the "blob" even on an attic distro like RHEL6: The most recent version of the NVidia proprietary

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #66 from Andreas Loew <awl1 at gmx.net> --- A Happy New Year to everybody! :-) Just wondering whether you intend to simply close this issue down with the workaround "solution" for me to set kernel option nouveau.config=PCRYPT=0 or whether you are still interested in finding out *why* my Quadro NVS 130M and other

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #37 from Andreas Loew <awl1 at gmx.net> --- Hello again, Ilia, ok, I see - did some further reading and I think I now fully understand the way it works: This also means that you are NOT regularly pulling the updates from Linus' central git into the nouveau git, but typically only do this ONCE after Linus released a new
