FC3 reboots if more than 4gb ram
Hola all,
I've installed FC3 on a dual opteron 246, iwill DK8S2-Sata mobo, 8Gb mem.
Right after the os chooset screen it starts to load the kernel then reboots. After the reboot it will boot up fine. Howver it needs to boot right he first time!!
This problem only occurs with over 4Gb mem.
FC2 boot fine.
Any suggestions!!!!

p.s. this happens with both 2.6.5 and 2.6.10-1.12

kernel support for +4G ram
--processer type/features->high memory support
...wish i had that problem...

I have been told that the kernel should auto detect and support the +4Gb as does FC2.

You may need to recompile your kernel or check that your kernel is actually preconfigured to use memory over 4gb. Seacrch the Fedora forum and google, I am sure something similar to this was asked a few weeks ago on this site.

Hehe. I was going to say exactly the same thing but you beat me to it. :)

Might be a silly question but what do you need 8 GB of RAM for?

secesh 02-10-2005 05:56 PM

what do you need 8G for?!?! because you can get it, claro!!!

--servers have higher demands, and need more hardware. Ram/processor capabilitits in particular.

heh, this is the head node for a 60 node cluster.
Hence the need for 8Gb ram. We have graphics workstations with 16Gb ddr2...just to make you drool.....he

I worship you. :eek:

Thnak you all, I had to contact iWill and they had a bios specifically to support +4gb ram.
Thank you all for your responses.
