i am running 10.04 lucid LTS with
https://launchpad.net/~falk-t-j/+archive/lucid added (lucid has linux-rt in
the repos, and falks PPA has the realtime kernels from
https://launchpad.net/~abogani/+archive/ppa )... the presonus firepod works
great for me even at lower latency settings... i can usually push to
1.2msecs if needed, and around 5msecs is very stable... i run both an
ubuntustudio 64bit install, and a 32bit vanilla ubuntu install that i added
some ubuntustudio metapackges to... both have falks PPA added...
