This is weird. With the preempt kernel, I get an xrun every time I
start reading the ac3 stream on sata disk. Not other I/O on the sata
device:

No, it's a 32 bits monocore (Barton XP3200)

Here we go:

No, sorry. AC3 output is still practically cut off when I run md5sum.

sata_sil depends on libata. So the libata counter is the one you're

No change at all. The ac3 stream still has so many drop-out it's quasi
mute.
Here's the command (with output) that I used:

No. they do not share the same interrupt. sata/libata is on irq

Hello
While watching hi-definitions video, I've noticed a lots of audio
drop-outs when watching movies with raw ac3 on spdif output (ac3
decoding is done by my Yamaha amplifier).
Long story short, I've been able to reproduce the problem when playing
a raw ac3 stream with ac3dec while loading my
