I understood that it was in the present kernel but I am repeating what
was mentioned on the nvidia support forum. But other things I am
reading is that you are correct. If it isn't the CFS, then the posters
comment on the nvidia forum was in error. What I do see is that some of
the CFS code is supposed to be in the kernel though, part of CFQ (?) I
don't understand enough of the coding to fully understand.
But on the Linux Kernel Mailing List, there is a thread on video issues
with the CFS.
I know that on my machine at home, even the gnome splash screen will
freeze the system. ssh into it and I see that Xorg is in the 95% range.
I went to an earlier version of the nvidia driver (I need 3D) and I will
have loss of mouse or keyboard from time to time. If I use mplayer and
change the speed using the "}" key, I lose all input. Strange screen
flashes but I don't end up with a total machine freeze. In gqview, if I
quickly go through images using the space bar, the display will flash
like it loses scanning.
This is using the Freshrpms and dkms tools. I have to find some time to
play with the latest kernel and drivers to see what happens. I am
hoping for an evening of rain to give me a reason to stay in the house
and not do yard work or go in the pool. :)
I have read about this same issue with different video cards so it isn't
just nvidia video cards. There is a bug report on bugzilla about a
I am also reading about this happening on different versions of Linux.
Due to the move to Exchange Server,
anything that is a priority, please phone.
