Is this your complete dmesg ? Check the other thread titled "pvops bug" too.

hi,

On the latest stage unstable kernel, I can boot Dom0, but dmesg
reports some warnings like below.

It seems something is wrong with AGP initialization?

I am using Core 2 Duo T9400, AGP GM45 chipset.

Any idea?

Thanks,
J
