Xorg does not start with GT520 and kernel 3.9.9


My just released Gentoo based 64 bit Distribution works fine with kernel 3.9.9 and nvidia 325.08 and most NVidia cards.
But I have two users with the same HW Combo:
Asus GT520 + ASRock H61M/U3S3
and both system do not start X, it ends with:
[ 20.881] (II) NVIDIA(0): Virtual screen size determined to be 1920 x 1080
[ 20.915] (**) NVIDIA(0): DPI set to (100, 100); computed from “DPI” X config option
[ 20.915] (–) Depth 24 pixmap format is 32 bpp
[ 20.915] (II) NVIDIA: Using 3072.00 MB of virtual memory for indirect memory
[ 20.915] (II) NVIDIA: access.
[ 23.917] (EE) NVIDIA(GPU-0): Failed to initialize DMA.
[ 23.917] (EE) *** Aborting ***

I tried all available version in the gentoo portage ( 304 310 … 325 ) each version shows the same error. The same HW combination works flawlessly with 32bit kernel 3.2 and nvidia 290 driver.

Unfortunately I just lost the the Bug report due to a reboot, I will collect this one tomorrow.


P.S. Which part is responsible for the usage of 3 GB virtual memory ? Can this be reduced ?

And here is the report

Now I tried it with disabling DRM in the kernel and unsetting DMA_SHARED_BUF but the result remains the same. Also disabling IndirectMemoryAccess in the xorg.conf does not help.

Any more hints what I can try ?

Hi Guys,

Sorry for the impatience, no ideas what else I can try ?


Internally Filed bug 1357839 to track this issue

Helmut, can you try disabling uvesafb and see if it helps.

From your logs file I see…

[ 0.672286] uvesafb: NVIDIA Corporation, GF108 Board - 1071v101, Chip Rev , OEM: NVIDIA, VBE v3.0
[ 0.725433] uvesafb: VBIOS/hardware doesn’t support DDC transfers
[ 0.725518] uvesafb: no monitor limits have been set, default refresh rate will be used
[ 0.725908] uvesafb: scrolling: redraw

Hey guys, I am not able to find exact Asus GT520 gpu, Is this happening with any other gpu?

Is there any process on this topic ?
The problem still persists and I got the same error with a Zotac H77 ITX Board with onboard GT620.

I am reporting that I was able to fix it in my scenario:
