Started a dual intel machine up running fedora core 10 linux. This machine has done MW w/u's before fine. Not this time. Downloaded the first w/u and it errored straight away with "SIGILL: illegal instruction",
This machine is running seti and Einstein fine.
Its fc10 (2.6.27.5-117.fc10.i686)
Same thing with a fedora core 8 linux with dual AMD cpus. (2.6.23.1-42.fc8) This has run seti for ages fine.

Both machines used to run MW fine. Any thing changed?.

Seeing similar issue this morning on my linux box. Found boinc client down... on attempted restart got the following:

This is probably my fault. It looks like I accidentally built the 32 bit Linux one with SSE2 and the old processor doesn't have it.

Not sure about this one.

Haaaaa, I thought something must have changed. 2 out of 2 machines with a fault looked a bit iffy.
Are we going to have a new app?.

I only have 1 windoz pc. The others are all linux of one sort or another

Ummmm is this a linux problem or an old cpu problem. I dont have a "modern" cpu running linux to check. And I dont have an old cpu running windows xp to check.
If its a SSE2 issue its not an linux problem is it??.

Just checking

I seem to be seeing a problem on my CentOS 5.5 x64 machine running a nVidia GTX 275. System appears to have received a recent kernel update (over weekend). As a result, I also upgraded the GPU device drivers from nVidia (dtd 11/11/10). Since then, I seem to be seeing frequent compute errors
(machine ID 194981).... most message indicate within task info following error:
Error executing gpu__integral_kernel3 error message: unknown error


Any suggestions for repair?

I have since moved my NVIDIA driver back to the prior release (oct 2010) and driver / GPU seem to be performing well on this project and others.
