If so, where is the solution? thanks in advance/bob ------------------------------------------- This happens when I HUP the pppd process, or it gets a signal from loss of carrier. Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0x0 stack pointer = 0x10:0xefbffe1c frame pointer = 0x10:0xefbffe74 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 148 (pppd) interrupt mask = net tty panic: page fault It started when I compiled a kernel that had "controller snd0" and "device sb0", using either the /sys/i386/isa/sound directory as delivered in FreeBSD-2.2-960501-SNAP/src/ssys.tgz, and also with the replacement .../sound in Amecio's vat modifications. I now realize that the same happens if I have Xserver support and no sound. This seems pretty basic. Advise appreciated.
