Hi, I'm having this problem since a while ago and I'm trying to trace the origin of it. I'm a 3d-compositing artist and use several related aplications, among them Maya, Mari, Nuke, Hiero, Mudbox, etc.This problem only happens when I'm using Mari (by The Foundry), which is the most resource intense piece of software I run. I used to run Mari previously with my outdated system with no problems appart of the expected ones; I mean, I use a dual Xeon QuadCore workstation which used to have 8 GB RAM and a Quadro FX 1700 GPU and the system crashed when trying to go beyond its capabilities. Then I updated my system, I installed a Quadro K4000 GPU, now I have 16GB RAM, added a new 500GB 10000rpm hd. I installed Windows7 on that HD, and Centos 6 on the other fast disk (a 150GB 10000rpm one), I put the windows disk on top of the booting sequence and modified the loader usin EasyBCD, to being able to chose OS (I think maybe this is the problem, but cannot be sure). Everething goes alright, not a single crash ever, but when I use Mari. Mari is intended for painting very high resolution textures, using the whole power of the GPU and writes project assets to a cache location you can select. I'm sure it's not a problem related to Mari (as I said I could run it better in my old system and there are not reports similar to my problem), and I'm able to run it for a while with full performance, until when, sudenly, with no specialy high resourse use, it hangs, sometimes straight to a blue screen, sometimes freezes the system with no other remedy than phisically shuting down the system. After either of this situation, system restarts but, before OS loading , next error shows:
0200: Failure Fixed Disk 0
and it fails to go on, then I must, again, physically shut down system, after this I start the system again and everything goes OK. But it always happen, sooner or later, whatever I'm doing with Mari. According to my BIOS, Disk 0 is the 150GB HD where Linux is installed, disk that's not even "visible" for windows (it's formatted using ext4 file system). I tried everything, of course I tried different locations for Mari's cache, but it happens anyway, now that this cache is in my C: drive (500GB hd) sometimes Mari fails to write data into it, logical, somehow disk is crashing (but I repeat, and I'm not sure about previous error syntax, in my bios disk 0 is the one where centos resides, and my windows C drive is disk 3). I should add that I had and have other disks for data,and one of them is connected through a PCIE-SATA card, all the others directly to the motherboard SATA inputs.
No one gave a solution yet, but someone from support staff where I bought the computer (it's a 6 year old motherboard, but it shoul go OK I think) sugested it might be a problem related to the boot sector in the windows partition and that I should probably try to reinstall OSs and use the old known method of choosing OS using GRUB....
I'll try thatif necesary, but I'd like to be sure since it implies spending at least a week installing stuff...
GPU passes every test, memory tests are Ok, event logs tell me nothing special...and everything goes like a charm until I'm doing what I said, what, bye the way, is one of thwe main uses of my workstation.
Well, I hope I was clear enough and I'd appreciate any suggestions. Thanks in advance.
