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 #73 from Andreas Loew <awl1 at gmx.net> --- Yes, definitely, a RHEL6 stock kernel is *very* old (2.6.32.*) - but due to a kernel drm/nouveau module update from 3.x source that they recently did for RHEL 6.5, it also suddenly became new enough to make me see this issue... ;-) Have just successfully applied the updated patch to

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 #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

I'll update the bug when this makes it upstream (or if we have further questions about your hardware). FWIW I've been going around asking people to report registers 1540/154c to me, and so far everyone except you and one other person having trouble with

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

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
