Maverick and RT
Hello all, I might be able to help out testing and once I become confident enough with packaging I could help with some of the other aspects of maintaining a kernel. It would be great if a real-time kernel would be available for 11.04 again, which depends of course if there will be a real-time patchset available for the kernel 11.04 will ship with. Afaik the current RT patchset maintainer is Thomas Gleixner. But I'd like to stress that I MIGHT be able to help out, it also depends if other people want to participate and if I have enough time (I am before all an active musician). Speaking for myself, I can't work without a real-time kernel. I need the tasklet API that a real-time kernel provides so I can use rtirq. Without rtirq my FireWire devices don't work properly at low latencies or don't work at all. And even on systems that run well without a real-time kernel I prefer using such a kernel so that I can get the best performance out of my systems.
