Hat`s off to you 67GTA,
I don`t know what those errors you fixed were but the new dsdt made a big difference. My hdd head used to hit the far end stopper every now end then and it sounded like a ball bearing bouncing on a hard surface. No more of that annoyance. Now the kernel and ubuntu actually works well with my hardware. `Cause it used to work around it`s quirks due to a buggy dsdt.
You should have "The Dsdt Debugger" written under your nick.
Applause to 67GTA =D>
