Hi,
I am crossposting this to LAD, because some low latency people
reside there.
Resume: I suddenly experience larger latency with my ens1371
It seems that is it not alsa, because other people with the
same card don't have this problem. I did update my system
from RedHat 6.0 to RedHat 6.1, but with my previous kernel
(2.2.14)

I *am* running as root. This is really very frustrating. I used to have 128
latency as well, now i need to set it to 1024!

As regular user my results are even worse.
