I noticed in 4.0, 4.01, 4.02, and 4.03 i can't run mersenne prime test. I've tried it on tons of cds, different images, and many other computers. No luck.

What is the observed problem? Did it hang, or spill out an error message?

Hi, new guy here
Not in the habit of hijacking other people's threads, but I've been having problems with prime since UBCD 4 was released.
It seems to be isolated to AMD64-based hardware, never seen this happen on Intel hardware.
The error I get is:
attempt to access beyond end of device
01:00: rw=0, want=4559, limit=4096
Segmentation fault
and it leaves me at the command prompt.
To me, it looks like a problem with the linux environment, rather than prime itself, but my knowledge of linux is very limited, so feel free to correct me
Thanks for your time.

First of all: nice softwarez!!! TY @ all
i got a similar issue!
My system: AMD AM2 X2 6000+ & 4gb RAM & MSI K9N & ATI 1950Pro (nothing else installed except CD and 1 Harddisc)
got the following error message when starting prime:
01 :00 : rw=0, want=4559, limit=4096
segmentation faul
Memtests with 0 errors and the other CPU test also with 0 errors
why is that? any solution? suggestion? help?

I have the same problem but with INTEL P4 1900MHz processor. Exactly the same system but with celeron 2400Mhz works fine so i thoght the CPU was busted but i see more have the same problem so it must be something else.

I get the exact same message on 2 different moptherboards. One is a Gateway board, the other is an MSI MS-6754. Both have P4 1.7 GHz CPU with SDRAM (not DDR) and Intel Chipsets.

Test the new cpustress image, available at:
viewtopic.php?t=1476
it will also detect multiple CPUs.
I think that the ramdrive wasn't big anough (mprime writes to the ramdisk).
All other CPU test programs don't write to the ramdisk, so they won't give you that problem.
