Hi, my project is currently running 4.4.9 with the PREEMPT-RT patch. We may need to upgrader our kernel. We're constrained by the vendor of our SOM in what kernels we can use, and at this time and the foreseeable future, we only can use 4.9.34 or 4.9.39. I looked on the PREEMPT-RT site's list of patches, but I don't see one for either of those versions. Just for the sake of trying, I attempted to patch 4.9.39 with 4.9.40-rt30, but to no surprise that failed. Do I have any other options? Does a non-published PREEMPT-RT patch that would successfully patch 4.9.39 exist somewhere I haven't looked? Thank you for any help, Brian -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
