[ubuntu-x] Q-series LTS Backport - poor hard disk write performance bug

[Aaron C Johnson]

I would like to post a bug for the linux-image-generic-lts-quantal 
package.  I guess since I'm not a team member I am unable to post to the 
Bugs section on launchpad.

I am running Ubuntu 12.04 32-bit on a brand new Toshiba L840 laptop and 
this bug is really driving me nuts. I am unable to have a stable system 
because I am being haunted by another kernel bug on the stock 12.04 kernel:

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/993187/+index?comments=all

Now with the 3.5 kernel the video issue is resolved but it is just as 
unusable because my hard drive write performance drops down to 40-70 
Mbps which really isn't the problem; the problem is that over a short 
period of time the write performance on my drive will drop down to 
something like 1.5 Mbps until I reboot...

I will post more details, dmesg output, logs, etc. if I can post an 
official bug for this package.

Thank you,
Aaron Johnson
