Well, the odd thing is that I have the exactly same setup on another machine with the same kernel rpm installed and that one has shm just fine. At any rate, according to Mdk there needs to be this kind of line added: none /tmp tmpfs defaults 0 0 (supposedly tmpfs has replaced shmfs in the newer kernels) Yet, I am not sure whether this thing has to be mounted explicitly or what. On the other machine everything is automatic, but this one is giving me all kinds of headaches. Should I maybe recompile the jack, now that I've added this thingy to my fstab? What about a reboot?
