I knew i am a special person ..... OK,ok my Computer is. SCNR ;)

Erm..

Well you do not even know how much i await eagerly your input Scott James Remnant.

In the meantime i installed Ubuntu complete new.
Since I have /home and /var/cache/apt/archives/ on seperate partitions this was just some time to spend and nothing to lose.

Damn is Dapper fast. ;)

After your mail I put the hdparm konfiguration back in place and was able (after some reboots) to repeat "the error".
Before that Dapper boots really fast, i was suprised.
The time from power on to gdm took only maybe 20sec i think.

Now after i turned on dma it´s like up the pole.

Here my data:

> When you boot the computer, press Esc to get into the boot loader menu
I have set:
timeout 7
in /boot/grub/menu.lst

and yes before i added the hdparm config in /etc/hdparm.conf everything was really smooth and fast.

Thank you Scott James Remnant
