recently i catched the following panic on my system :
fatal trap 12: page fault while in kernel mode
fault virtual address = 0x8
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc05b4886
stack pointer = 0x10:0xd741ec94
frame pointer = 0x10:0xd741ecb0
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 = 28 (swi8: tty:sio clock)
kernel: type 12 trap, code = 0
stopped at nd6_slowtimo+0x46: movl 0x8(%eax),%ebx

this panic occured several times a day. it does not seem to make any
difference whether there is high load on the system or not. i get the
same error with and without acpi.
first, i thought this was a hardware problem, so i changed some of
my hw-components (vga, mem) and still got this error.
then i found out that nd6_slowtimo has something to do with inet6. so i
disabled "option INET6" in my kernel config - et voila my system runs
stable (for several days) now.
anyone similar problems - or is this a PR ?
