I get as far in the installation as answering all the questions and clicking the install button. The system just panics. My system is a ASUS-SP3G, AMD-5x86/133(it also burns with my i486 dx2/66), dirty tag on L2 cache. ktrace does not give me anything, DDB does not save the core it just burns. Does anybody know what I can try next? I'm running -current 3-24-96. gargoyle /kernel: Fatal trap 12: page fault while in kernel mode gargoyle /kernel: fault virtual address = 0x0 gargoyle /kernel: fault code = supervisor write, protection violation gargoyle /kernel: instruction pointer = 0x8:0x1 gargoyle /kernel: code segment = base 0x0, limit 0xfffff, type 0x1b gargoyle /kernel: = DPL 0, pres 1, def32 1, gran 1 gargoyle /kernel: processor eflags = interrupt enabled, resume, IOPL = 0 gargoyle /kernel: current process = 1421 (xwpinstall) gargoyle /kernel: interrupt mask = gargoyle /kernel: panic: page fault Eric J.
