Has anyone found/fixed this bug? 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.
