Hard disk error after installing ATI drivers

Asked by Derek

Hey guys,

I'm new to Ubuntu so please bare with me.

I installed Ubuntu 10.10 no problem. Got into the desktop no problem. I wanted to enable the ATI drivers. So I used the application in, System -> Admin -> Additional Drivers.

It installed the drivers and rebooted. While rebooting it throws a hard disk error:

ata3: exception emask 0x0 sact 0x0 serr 0x0 action 0x10 frozen
ata3.00: failed command: identify device

If I leave it, it eventually starts up X.org. If I remove the drivers using the same program, it boots up without the error.

I have an ATI HD 4850 video card.

When installing ubuntu I used the 'install along with another os feature' (windows 7) and selected one of my non mission critical hard drives, and let the ubuntu installer re-partition it.

Anybody have any idea what's going on? Searching google and this forum wasn't much of a help. :(

Cheers,
-Derek

Hi

some forum posts [1] suggest that configuring grub to start with 'acpi=off noapic' may solve that problem.

Awesome, thanks for the lead. It worked!

Here are my notes for other noobs using Ubuntu 10.10 and GRUB 1.98

Open up the terminal. Applications -> Accessories -> Terminal

We're going to edit the grub config file using:

sudo gedit /etc/default/grub

Find the line:

GRUB_CMDLINE_LINUX_DEFAULT =

And add:
acpi=off noacpi

My line looks like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off noacpi"

Happy hacking!
