I have a new Fedora 18 system which every few days will freeze completely - not pingable, keyboard and mouse not working, screens off.


Intel Core i7 3770K CPU
Asus P8Z77-V LX MB (with up to date BIOS)
32GB (4x8GB) Corsair DDR3 Vengeance
2xWD Caviar Red 2TB hard drives (software RAID 1)
2 x Dell 24" (1220x1200) monitors on HD 4000 onboard DVI and HDMI ports
750W Corsair Power Supply


Fedora 18 with the latest updates (kernel 3.8.4-202.fc18.x86_64) Cinnamon desktop

The freeze is completely unpredictable, most often happens when system is not in use with screens powered off by software. After power down and boot system is fine again.

There are no indications of errors in any log files.

Any ideas? I have read about similar hangs with HD 4000 graphics but that problem seemed to be fixed by Kernel 3.2. Could having two monitors make a difference?

Do you use RAID (mdadm) or VMWare?

Are you still experiencing this problem?

I'm experiencing a similar problem. My system freezes every 24-48 hours. Because I run it 24x7 the freezes happen when I'm not behind the keyboard. However /var/log/messages has no related info to the crash (I leave a terminal with tail -f running).

I first experienced this on the latest kernel of CentOS every 24hr or less but, after moving to Fedora, the crash occurs after a longer period. I can also confirm the system is really frozen, I can't ssh and all the services I run, samba, plex, and vmware, are unresponsive.

Finally the last piece of information, I too am running an ASUS motherboard, P8H77-V LE (latest firmware). Before I was running on an MSI (based on H67) but did not experience this problem. My CPU is a 2600K and I'm using the HD Graphics 3000 (no GPU card).
