hi

i hope this gets to the right person...

keywords: overlay/video/agp/disk/io

i have got the following problem:

when using video overlay (watching dvbs-tv with kvdr or xawtv) and at the same same time
copying a file; the system completly freezes after 3 up to 10 seconds.

i have got a KT600 chipset. it only happens with an agp card (testet matrox g550 and
nvidia cards). with a pci card it does not occur..


testet with 2.4.23 and 2.6.0-test5 to 2.6.0-test11, 2.6.1, 2.6.2, 2.6.3 ..
