I don't have errors that are on the monitor when it hangs (there is something about Bug: spinlock on cpu#0 java/2 0192 f765e834 (not tainted)) but when restarting after a hang it gives: > Use "memtest" to verify the RAM is okay. If you boot from a fedora CD, this is available as a boot option. I had a similar error from an FC4 box (co-incidentally), and memtest found the RAM was faulty. Let the memtest run for a couple of complete passes. Cheers, Ben
