Linux and Intel Core 2

September 3, 2006 Comments off

After resurrecting my old Intel Celeron system with Ubuntu 6.06 LTS, and finding it to be too slow for my liking with the Gnome graphical interface, I decided to upgrade the hardware. I don’t recall my Intel Celeron system to be that slow. Really, I am starting to believe that Intel chips have a decay mechanism built in.

So I got myself an Intel Core 2 E6300, supported by a Gigabyte GA-965P-DS3 motherboard, 1GB RAM, and a SATA Maxtor 320GB harddisk. Not too bad, right? Although it’s not the highest end of the Intel Core 2, but should be a drastic improvement over the Celeron. Furthermore, I’m not a hardcore gamer, so that should be fine.

Alas, the hurdle that stumped me for 3 days was that most of the Linux distros have problems with the Intel 965 chip. During the installation, Linux will have a problem trying to mount the CD-ROM, hence installation will stall at that part. Apparently, it’s a bug in the Linux kernel, which will be fixed in the 2.6.18 version. But I can’t wait that long.
The only distro that I have found that can install is Red Hat’s Fedora Core 5, and you have to do the following:

1. Modify your BIOS to use AHCI mode for your SATA/IDE drives.

2. Start the installation with “linux install all-generic-ide”.

I hope that helps you. You can read more about the problem here.  A wiki page in Ubuntu on this issue is now available!

Looks like I’ll have to stick with Fedora Core 5 for a while. At least until Ubuntu 6.10 is out. It will be a good opportunity to try out Fedora.

Davicom network card with Tulip driver

Just doesn’t work in Ubuntu 6.06.  This problem was fixed in the package for 2.6.15-24.40, and the latest kernel from dapper-security should no longer have this bug.

But if you still have this problem, you can do this:

sudo sh -c ‘echo dmfe >> /etc/modules’

sudo sh -c ‘echo blacklist tulip >> /etc/modprobe.d/blacklist’

This is to load up the dmfe driver on boot up, and blacklist the tulip driver.

Ubuntu 6.06 hanging on IBM ThinkCentre A30 after non-activity for more than 24 hours

Linux 2.6.x, which Ubuntu 6.06 is based on, hangs on IBM ThinkCentre A30 after non-activity for more than 24 hours.

My scenario is that when I come back to office after the weekend, my linux system takes very long (about 2 minutes) to respond to any keystroke or mouse click.

IBM has a BIOS patch for it:

If you want to know more about the problem, you can read it at:

The other solution is to start up the kernel with the “noapic” option.  You can edit the /boot/grub/menu.lst file and add in the “noapic” in the boot command for the kernel lines.
