Hi Thomas > I'm pleased to announce the 3.6.9-rt21 release. 3.6.7-rt18, 3.6.8-rt19 > and 3.6.9-rt20 are not announced updates to the respective 3.6.y > stable releases without any RT changes There is some progress here. It boots but sometimes i see the backtrace below. Also: Has s.th. changed in respect to the modules. I have one module wich goes on an endless interrupt loop freezing the device. The driver works fine for 3.0 - 3.4 preempt rt kernels? This is a miscdev based driver. If someone is interested i can post the source over here. But unfortunatly i have not figured out why this thing goes to an endless interrupt. The identical driver works flawless on 3.4. As always i have some platform adaptation code applied but nothing serious/different from the 3.4 patches which work fine.
