Performance issue with 5.4-RELEASE-p8 but not with 5.4-RELEASE

[Lukas Razik]

Hello!

Today I've done a cvsup to 5.4-RELEASE-p8 and built a new kernel.
But now I have problems with xine because if I watch a DVD then I get about two short freezes per second.
With my old 5.4-RELEASE kernel I have no problems and the config is exactly the same...

Does anyone know a solution for this problem?
Is there a tag or something else which I can use in my cvs-supfile to go back to 5.4-RELEASE?

Many thanks in advance!
Lukas
