The only thing I see there is that commit 103fbf8e4020 ("scsi: megaraid_sas: Added support for shared host tagset for cpuhotplug"). Of course, it could be something entirely unrelated that just triggers this, but I don't think I've seen any other reports, so at a first guess I'd blame something specific to that hardware, rather than some generic problem that just happens to hit Jula.
