Comment 113 for bug 621265

I'm experiencing the same issue, I've been testing it by copying files from a server in my house using FTP. Transfer rates average 200KB/s or so with the Maverick kernels, however if I use the 2.6.32-21 Lucid kernel I get speeds of 3MB/s!

Here's how I installed the Lucid kernel...

Add these lines to /etc/apt/sources.list:
deb http://us.archive.ubuntu.com/ubuntu/ lucid main restricted
deb-src http://us.archive.ubuntu.com/ubuntu/ lucid main restricted

sudo apt-get update
sudo apt-get install linux-image-2.6.32-21-generic

This installs the image, but since it's an older image, grub doesn't boot to it. You have a few options here. You can try to press ESC on boot to get into the grub menu then manually select the 2.6.32-21 image. I have a hard time with the timing and miss it often. To increase the timeout edit /etc/default/grub and increase the GRUB_HIDDEN_TIMEOUT to something like 5. That gives you more time to press escape.

To make it boot 2.6.32-21 by default, get into the grub menu by pressing ESC right before Ubuntu boots. Count the grub menu entries to the kernel you want, mine was entry 6. Edit /etc/default/grub and change GRUB_DEFAULT=0 to that number. Now your system will boot that kernel automatically.

It works great for me, I know some would rather have a fix for the 2.6.35 kernel, but I don't know of any improvements in 2.6.35 that I need!

Thanks,
Chris
