according to my observation 2.6.19-rt15 is based/includes 2.6.19.1 changes. But there has been that nasty clear_page_dirty_for_io() bug causing corruption of ext3. Even that I have tested more 2.6.20-rc + rt, I preffer to stay on "stable" kernel on boxes which I use daily until next stable appears. I have backported clear_page_dirty_for_io() to 2.6.19-rt15 and it worked fine. I have tried to update 2.6.19-rt15 to 2.6.19.2 base. There is result of my attempt Unofficial incremental patch from 2.6.19-rt15 to 2.6.19.2 + rt http://rtime.felk.cvut.cz/repos/ppisa-linux-devel/kernel-patches/current/patch-2.6.19.2-incr.patch Kernel seems to work correctly. I have checked the patch contents and I have not noticed any RT problematic changes in the code according to my dumb knowledge. I would be very happy, if Ingo would be so kind and could confirm my findings, because I am not sure, if final 2.6.20+rt would be ready before we need to prepare setup for our next semester classes at university.
