Hi, > With today's init_main.c, the system still hangs if the boot-device > is IDE. I believe that there is a conflict between the kernel and > APIC stuff (built in ID controller in Tomcat and Tyan Titan). this is good news! So I think we may be past the general "system hang" problem. Is there ANYONE out there that still has this problem after applying todays (96-11-30) kern/init_main.c?

It is believed that its caused by our failure to do tlb flushing during page stealing. Peter's working on an implementation of IPI's to trigger tlb flushes, which should fix that problem.
