xmms child blocked at end (2.4.18pre1)

[Jorge Nerin <comandante@zaralinux.com>]

Hello, I have a very strange thing here.

I have a 2x200mmx using 2.4.18pre1, xmms 1.2.5, xawtv-3.61 and XFree86 
Version 4.1.0.

The situation is that I have a nfs mounted share with mp3, using xmms to 
play them, (3c503 over coax) everithing goes well until I put xawtv in 
fullscreen mode. I don't know why, but at this time in short time the 
child thread of xmms blocks for a long time in end, having xawtv in a 
window does not cause this.

Here is a vmstat 1 log:

The only blocked task is xmms child, as I said it's blocked in end, so 
it empties it's buffer and you can hear it

Another thing I have noticed is that when I have a big transfer with 
this card (I have another 3c595) and having xawtv in full screen I can 
see dropped frames, I assume this is for the speed downgrade of the pci 
bus to acomodate isa tranfers, the 3c503 is a very old isa nic, and my 
tv capture is a pci bt848.

Don't know if this rings a bell of somebody.

P.D. Sorry for my bad english.
