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 #46 from Ilia Mirkin <imirkin at alum.mit.edu> --- Well, given that it doesn't work on the blob makes it sound like you have some sort of funkiness in your hardware. 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 #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

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 #64 from Andreas Loew <awl1 at gmx.net> --- Yes, we indeed see the same well-known: nouveau E[ PBUS][0000:01:00.0] MMIO read of 0x00010000 FAULT at 0x10200c at any nvpeek read attempt, and nouveau E[ PBUS][0000:01:00.0] MMIO write of 0x00000010 FAULT at 0x10200c at any nvpoke attempt... :-( BR, Andreas -- You are

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

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

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
