I've been using Ubuntu for pretty long time and am quite experienced with it. But recently I discovered a new problem that I can't resolve on my own.
My system is as follows:
- AMD E-450 1.65
- AMD Radeon HD 6320 with latest ATI Catalyst linux drivers
- (AMD Catalyst 14.12 Omega linux drivers)
- Ubuntu 14.04.02 64 bit system is up to date - a fresh installation
- kernel - Linux 3.16.0-34-generic
- 4 Partitions: Swap 4GB, Ubuntu 80 GB, Windows 7 160 GB, Data over 200 GB
- using burg for system choose with better splash look
When the system is booting I see a line with:
[ 2.459938] ACPI : [Package] has zero elements (ffff880232749800)
After that the system seems to work as it should maybe slower sometimes it stuck for a few sec and work again and it's quite annoying to see that kind of line under boot.
A few months back when 14.04.01 was the latest Ubuntu version everything was perfect until 14.04.02 came out. I tried every possible way to resolve that problem: I wiped and did a fresh install again, changed drivers, kernel etc. But without success. It must be something do with 14.04.02. Something seems to have changed and created the problem but I don't know what exactly.
It doesn't matter if I change drivers or even kernel version. I tried from 3.13. to 3.19 last stable and problem still is there.
When I add
acpi=off noapic to boot line the problem is gone but the system doesn't work normally.
As I wrote above even after a fresh installation without any changes the problem still shows. I though maybe it happen after my changes in system but its not true.
I read a few topics with ACPI has zero elements but all goes to use line
acpi=off and they were very old for Ubuntu 11.04 or 12.10.
Does anyone have a idea how to resolve this?
