https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #49 from Andreas Loew <awl1 at gmx.net> --- OK, tired with RHEL 6.5 kernel 2.6.32.431 and the two options: Command line: ro root=UUID=034d34cd-a464-4ee3-8db9-d6061a318a16 rd_NO_LUKS LANG=en_US.UTF-8 KEYBOARDTYPE=pc KEYTABLE=de-latin1-nodeadkeys rd_NO_MD SYSFONT=latarcyrheb-sun16 rd_NO_LVM rd_NO_DM nouveau.perflvl_wr=7777

One unsubstantiated theory is that the vdec clock is *disabled*, and pcrypt is hooked up to that clock. Or perhaps that clock is somehow broken. It'd be

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 #44 from Ilia Mirkin <imirkin at alum.mit.edu> --- Try commenting the same line out and see what happens... (i.e. the one with 0x74c1) FWIW I do remember seeing some PCRYPT-related (and PVP/PBSP-related) errors on start in the form of MMIO write failures in your log and thinking it odd: nouveau E[ PBUS][0000:01:00.0] MMIO

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #51 from Ilia Mirkin <imirkin at alum.mit.edu> --- So actually I'm told that pcrypt is on the main clock, so that theory is out. Can you grab envytools (https://github.com/envytools/envytools) and run nvapeek 10200c nvapoke 10200c 10 nvapeek 10200c and see what's in dmesg?Do you see additional MMIO read/write failures,

https://bugs.freedesktop.org/show_bug.cgi?id=58378 --- Comment #65 from Andreas Loew <awl1 at gmx.net> --- Oops - I just remembered that I am booting my kernel with "nouveau.config=PCRYPT=0" in the meantime... Does this make any difference, i.e. do I need to retry the nvapeek/nvapoke sequence without this kernel option? Sorry & thanks, Andreas -- You are receiving this

You should hopefully see a message saying that it and a few other engines are disabled. This needs

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 #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
