Just interest... Hhhm, well, I spottet a problem. The thing is that linux-rt does many deep changes in the kernel and I won't be able to support the harder problems. And upstream probably won't help because the Debian rt-kerne= l isn't a vanilla rt-kernel. Moreover even the broken out rt-patch isn't nicely sorted (e.g. bisectable, some patches undo changes of other patches earier in the series etc. pp), so I fear the Debian kernel team isn't filled with enthusiasm when asked to add an rt variant. I already thought about packaging debian-kernel + rt for Debian and vanilla-kernel + rt for a non-Debian package repository such that it's easy for bug reporters to try out a vanilla kernel. But that still nee= ds more work. I currently investigate how the Debian kernel packages are created. An= y help is welcome. Probably the first step will be to create a vanilla-r= t package, but that wont be accepted to go into Debian main.
