Hi, We've been working to integrate/support a new system board and have noticed boot-up stalls running 3.18.29-rt30 (in particular when the kernel is configured with PREEMPT_RT_FULL - as diagnostics markers, PREEMPT_RT_RTB and non-RT appear to be fine). The boot-up stalls appear fairly frequently - approximately once every 8-10 cold boots - and occur very early in the boot process. The SHB board houses dual Xeon E5-2680 v3 parts (i.e., 2x12 cores for a combined 24 cores). My question is regarding the v3.18 tip (currently v3.18.34) and whether an RT release for this version might be worthwhile to try. We'd consider moving to a v4 test branch, but ultimately we'd like to test a new v3.18 in order to determine impact in the field. I hesitate to ask this but am wondering if anyone might have some feedback on the time frame for an RT refresh on the v3.18 tip?
