Slooow starup with more than 4 Gigs RAM

mindink · 11-13-2007, 10:34 AM

I'm stumped!

I have an Intel Motherboard G33FBC. I have tried several distros (Suse 10.2, Fedora 7 and Mandriva Spring 2001) all for the x86_64 arch. With 4Gigs RAM and "acpi=off" I can install Linux and get the e1000 driver installed, update etc etc.
The crunch comes when I install an extra 4 Gigs RAM. Startup takes 20 minutes and everything is in slow motion. "free -m" shows all the memory.
Any Ideas?

Hate mail coming, Win XP 64 runs perfecto!

Check what kernel you're running. If you have 4 GB of RAM at install time, and add more later, that could cause this. You need the kernel-bigmem or the enterprise-kernel, for anything over 4 GB. You can always re-compile your existing kernel too, to add bigmem support.

Not sure what the problem is, but I do not THINK you should need to do bigmem with 64bit.

Thanx for your input.

I'm using the kernel that comes with the distro. All 64 bit. Mandriva 2.6.17-13mdv, Suse 2.6.18.2-34 Have used 64 bit Mandriva and Fedora on other 8 Gig machines before with no problems. I will check to make sure of bigmem support.

Installation with 8 Gigs is also terribly slow.
