Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Let the system idles for 20-30 min. Sometimes it take more than a day to reproduce 2.It seems when no one is talking to the system, it goes to sleep? haha 3.need further information? Actual Results: Nothing runs!! Can't login, can't restart, can't do anything. Should I go back to Windows? Expected Results: It should continue to run right? Additional info:
Is this an unmodified (hardware-wise) system, for example: non-overlocked? Have you run memtest86 (Google for it)?
Component == kernel
No. Everything is running with their default values. No overclocking what so ever. But I haven't tried memtest86. I am going to test it and let you know how it runs. Thanks.
memtest86 ran fine. Now what?
Hmm - that's strange. Could you please attach the output of "lsmod" (shows the modules that are currently loaded in the running kernel). Also - provide "cat /proc/pci". This will show all the currently attached PCI devices that kernel has found. There definitely appears to be a driver conflict or a hardware problem - seeing the configuration could be beneficial to Red Hat developers.
It certainly looks like a random corruption It would be good to know if this still occurs with current errata kernel.
