Hi,
I have built a new PC on which I've installed CentOS 5.5 64-bit (with updates) which after some hours of running suddenly either hard freeze or instant power off. The /var/log/messages log doesn't reveal anything of what has happened. The load has been either just idling or with moderate disc activities (transfers over 100GBit). Below is the hardware spec:
Motherboard: Gigabyte GA-H55N-USB3 CPU: Intel Core i5 650 RAM: CORSAIR 8 GB RAM HDD1: Intel X25-M 80GB HDD2-7: Samsung ECHOGREEN 500GB ST LABS SATA/300 4-PORT PCI-E PSU: Corsair CX 430W
I've also been running memtest86 for more than 24 hours without any errors.
I was on my way to return either the motherboard or the PSU when I thought of installing Fedora 14 and give it a try. The PC has now been running for over 48 hours without any glitch, with varying load.
I should also mention another problem that strangely disappeared with F14, and that was that the Samsung HDDs, which I have in a soft RAID6, now and then timed out (only one at a time). The message log showed a dump of NCQ queued commands, before it reconnected that disk. In F14 I haven't seen any errors at all in the log.
Could those problems only relate to C5, or do you think I also have hardware problems and only been lucky so far with F14?
Best Regards, Christian
