Re: Bad SATA devices performance

The problem comes when I burn a DVD ISO in a blank DVD.

I lost all my graphical interface to continue working in other aplications

When I say "lost", I want to say that all graphical system (and system
performance) slow down drastically. I notice that "average load" in
"gnome-performance-monitor" goes up, but CPU a bit loaded only.

Any tool, kernel param, or anything that allow me to diagnose and solve
this problem?

My laptop appears to have any intel ┬┐"ICH"? controller (I don't know at
this moment).

I have an IHC controller on my Toshiba Laptop. There was a kernel change some time ago that allowed my laptop to work with DVD's and speed up the speed of access. There are two areas to check.

The BIOS may be trying to run the SATA drives as IDE drives. There is also a flag for the kernel that will enable DMA for the SATA drives. The laptop is at home but I am at work. I sent the info home and this was one of the settings I changed.

libata.atapi_enabled=1 in the modprobe.conf file
