Hello!
I decided to write here too in case someone else has experienced this issue. In
specific, I have a Gentoo box dedicated to music production, 3D modelling and
Flightgear, aiding me with my pilot studies.
(Specs: Motherboard: Gigabyte EX58-UD5 F12, CPU: i7 920@2.80 GHz Quad core,
Memory: 12Gb RAM, GFXCard: Gigabyte GeForce GTX 260 896Mb, OS: Gentoo
Linux x86_64FG: current Git)
I've been having these issues with Flightgear Git (started with 2.6), the sim
and the entire system (except sound!!) freezing for 10-15 secs, from every 2 to
10 mins.
Dmesg reports:[ 140.311822] NVRM: Xid (0000:02:00): 8, Channel 00000003[
142.309503] NVRM: os_schedule: Attempted to yield the CPU while in atomic or
interrupt context
So far I've tried:Contacted the Nvidia team through the Nvnews forum (thread
with my logs and feedback here:
http://www.nvnews.net/vbulletin/showthread.php?t=177732 )Built 4 different
kernels, from 2.6.25, to 3.2.1, to 3.2.17-rt (!!), to 3.4.2 Tried these kernels
with stable and unstable drivers since September up to date.Tried Unigine
benchmarks in different setups, which ran with no problems or freeze-ups.
Now, I know that so far it seems kind of off-topic for this list, however there
are some points I would like to bring up which could (although I seriously
doubt it) be because of the sim or even OSG. These are:The bug/freeze does not
occur if I just stay on the starting point (rwy or parking). (No texture
loading...???!)The bug/freeze does not occur if I fly over sea. (RMK: The
console log was complaining about some .DDS sea-related textures not being
decompressed which could affect stability. I loaded and saved them with GIMP,
and now there is no warning. It could have affected over-sea flying
stability)2-3 months ago using the then latest driver I was able to sink the 3D
cloud distance at 25000m to prevent from having these freeze-ups. However, it
does not seem to be reproducible now...Flightgear is the only program this
freeze-up happens (with the exception of Blender, 2-3 months ago. Does not
happen now, as far as I have checked)
My apologies for taking your time. If there is any more info (logs, etc) you
would wish for me to provide, just let me know.
Best regards
