AMD Cpu's with VDPAU and IGP 8300 Framedrops on Driver 18.22

Hi,

i'm using xine-vdpau and have a stsange problem.

The hardware platform is :

Motherboard : ASUS M3N78-EM with the GF8300 IGP
CPU : Athlon X2 4850E
2GB 1066 MHz Ram.

Now the problem :

When running the CPU on 1GHz i get lost frames with xine-vdpau
on 720p content. The CPU utilization on this frequency is about 10%.

When running the CPU on 1.8GHz everything is fine. And the CPU
utilization is about 6%.

So from the CPU utilization there could be no problem. Any ideas
where the problem could be ?

Hm. Intresting that this is ignored, since it's a know problem.
And nobody is willing to tell if it's a hardware limiting problem
or a problem in the vdpau implementation.

It's not being ignored; it just took a couple of hours for me to see the post.

Judging by the (limited) information here, it doesn't sound like it's a VDPAU issue.

What about HT (hypertransport) speed ?

ebsi, do you have any problems like image corruption or system freezes? If no, could you write your driver, kernel and X versions

My system has a similar config and and it freezes with compiz.I am looking for the solution

Nvidia 8300 mGPU (Asus M3N78 PRO)

This is interesting. I have exactly the same MB, and a similar problem. I have as well already updates the BIOS a few times, up to 801 now.
I had problems with Ubuntu 8.10 and likewise with 9.04 recently. So let's take it that we have to make with a wide-spread problem.

Interesting is, that the system doesn't actually freeze, it only looks like. I can ssh into it, and everything is fine, no high loads, and in the end I can shut down cleanly.
Then the actual bugs comes to light: Even when X shuts down, usually showing the logout messages, the ubuntu thermometer; in this case, the last, stuck, frozen, frame remains visible until the power goes off.
So it is actually a bug, that for one reason or another prevents refreshing of the frame buffer, which actually gets inaccessible by the driver. This can be a problem of the nvidia driver, or the nvidia hardware. In any case, Nvidia is the party to debug this.

FYI, the following thread has some information on AMD CPU throttling interaction with bus bandwidth:
