I did the same quick latency tests with 2.6.12-rc1 that I posted about
for 2.6.11 a few weeks ago.
2.6.12-rc1 is significantly better than 2.6.11. Running JACK at 64

with "dbench 64", which slows the system to a crawl. With 2

Is this printk intentional? I am sure users will wonder about it,

Assuming it's still available, what is the config option to get the
"User-space atomicity debugging" feature? This feature is extremely
useful for debugging complex JACK clients, several Lin
