Fedora freezes frequently

[satimis]

Hi folks,

Host - Fedora 12
Virtualization software - KVM
Guest (VM) - Fedora 12, Ubuntu9.10, Debian5.0, Windows Server 2008
all 64 bit

The workstation freezes occasionally while browsing Internet.(VMs are not running). Press [Num Lock] - LED is not on/off. Ctrl+Alt+F2/F3 no response. I have to press hard reset to reboot the PC.

No warning indicate except once saying "metacity" not reponse. Please advise where to check? How to fix the problem? TIA

You probably have a hardware problem. Please run the system diagnostics if you have it available. Otherwise, get it from the system vendor website. Please provide as complete information about your hardware as you can for more help with this.

Hi Rubberman,

I don't suppose the RAM is ECC FB RAM (Error corrected, fully buffered RAM)? Anyway, you need to get the diagnostics from Asus and run over a period of time to see what is failing. It is most likely (not positively) the motherboard or RAM.

Just a comment. I always spec ECC RAM. At least when it starts to fail, the operating system will tell me, yet keep running. That is, when there are single bit errors occurring. ECC will handle single bit errors OK, correcting them on the fly, but multiple bit errors will cause a kernel panic in most cases, if the errors are in the same block of memory (most likely scenario). This has saved my bacon on more than one occasion. In any case, I don't EVER purchase a mobo that doesn't support ECC RAM. It just is not worth the pain and suffering.

Hi Rubberman,

Thanks for your advice. IIRC freezing only started after the crash of X resulted on running "yum update". Afterwards I couldn't do anything on the PC. Fedora12 was running. I can login only without X. On the following day I ran "yum update" again. It fixed the problem and X revived. From that time onwards each day I run update as suggested fixing many bugs. I'll hold on for several days to check what will happen.

That's good to hear. Sounds like a regression on one of the updated packages snuck through and bit you. That happens occasionally, but thankfully not often. Less often with Linux than Windows I think, though that's just my impression given my lack of enthusiasm for anything Microsoft...

I had the same problem. I changed to ubuntu.
In my case it was due to ATI videocard problems. Fedora freezes always after 4-5 mins and i couldn't use it.

I don't know if, using virtualization programs, the same problem can occur.

I've found that most of the time a system using an ATI card is not a good idea, just from my experiences anyways. Driver support is not well established. The new kernel coming out is suppose to have native NVIDIA support. So what does that tell you?
