Well, we are running the preempt rt patchset 3.0 since the rt-9 release and we have not seen this kind of error. It just started popping up after i applied the patch which i took directly from the mailing list when it was posted, since we had this ksoftirq issue especially after firmware update when ubifs has been updated. The bad thing is that it is not happening deterministic but seemingly at random. But i will try your next prerelease and will report any results. My patch is also not completly vanilla mainline. I am using the recomended patch from ubifs/master, some small platform patches and some timer patches Thomas Gleixner knows best about.
