>Description:
Use of ping -r mail (mail is the smtp/pop3 server on the TCI lan)
causes a kernel mode page fault. The transcribed output looks somthing like this:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x35000232
fault code = supervisor read, page not present
instruction pointer = 0x8: 0xf0194fe6
stack pointer = 0x10: 0xf4f94df0
frame pointer = 0x10: 0xf4f94df8
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL0, Dres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, 10PL=0
current process = 350 (ping)
interrupt mask =
trap number = 12
panic: pagefault
>How-To-Repeat:
This problem occurs any time I use `ping -R mail` (due to the severity of the problem i haven't experimented much with it.)
