Then, I made a little modify to the kernel config file (enabled DDB and "make -g") and I rebuilt all the universe (world+kernel :) ) Near the end of "make buildworld" the machine paniced. I copy here by hand the panic message, but unfortunately I have not yet learnt how to get a more useful backtrace at the "db> " prompt... if someone is so kind to teach it to me... (I'm still a newbie in kernel debugging :( ) Fatal trap 12: page fault while in kernel mode fault virtual address = 0x25 fault code = supervisor write, page not present instruction pointer = 0x8:0xc02632c4 stack pointer = 0x10:0xcdccee64 frame pointer = 0x10:0xcdccee68 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = = current process = 21029 (cc1) interrupt mask = net tty bio cam kernel: type 12 trap, code=0 Stopped at vm_page_unqueue_nowakeup+0x28: movl %eax,0x4(%edx) Now I'll try to reproduce the panic... -- bye!
