Why is my Fedora 10 hanging
 

Hi, I am running Fedora 10 and every 3 hours or so it hangs and I have to pull the plug. I have vmware that runs windows on top but I shut it down cause I don't really like it. Sometimes I am forced to bring up the vmware just to do my work. What could be the cause of this windows behaviour? Thanks.

unfortunatly you hanv't much information
there could be any of a bazillion things wrong that could be causing it from overheating to bad memory to a glitch in a program

as a start try posting the last say 20 or 30 lines of the output of dmesg

Hi, Thanks for your response. I must say I didn't know where to look. Here is tail output from the log. I have included messages in the log that seem suspect also. Does the system core dump when it hangs?
