There was some conflicts a while ago with Linux kernel developement and "real" realtime capabilities being brought into Linux.

Montavista and another company (maybe windriver?) had developed extensive modifications with the Linux kernel to make it realtime-capable.
see:
http://linuxdevices.com/news/NS3557180455.html

However they were not acceptable to Linus based on that they were very intrusive to the kernel and had code spread all thru out the system. This caused some friction...

Ingor was working on 'volentary preemption' stuff for a long time, I think, but when montevista and friends were fighting to get their mods into the kernel he went and started developing realtime-preempt heavily in a hope to get the modifications integrated into the kernel in the distant future buy doing the mods in a Linux-coding standards acceptable way.

I am not sure about this, but this is the general impression that I've got. MonteVista maybe using a lot of Ignor's code, but they have put a lot of work into the kernel themselves even if that work wasn't very accaptable to Linus ultimately.

I don't know if this is a very serious issue.

I believe the other company was Timesys (mentioned near the end of the article), not WindRiver. The latter is a recent convert and has not, to my knowledge, contributed much to Linux.

Part of my job is making sure that TimeSys continues to be active in the Linux kernel community.

FWIW, I've got about 80 submitted TimeSys kernel patches in my tracker. Not all have been accepted and most are admittedly minor, but we have been pretty active. We don't track our kernel patch submissions any more, so I can't give current data.

Scott Wood of TimeSys wrote the soft IRQ threads implementation in Ingo's patch set.

Jon Cooper is a TimeSys employee who is working full time with Ingo.

TimeSys is active, but we've been keeping a low profile. We're much more interested in seeing the work completed and accepted than in claiming that we did it.
