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.

"end" is the name, because the address is bigger than any known symbol.
I think it has something to do with pthread in general - since I observed
it several times with threaded apps (not only xmms)
