text dump
I wrote small program to test changes in ipv6 code, but it triggers panic in
generic socket's code.
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x1c
fault code = supervisor read data, page not present
instruction pointer = 0x20:0xffffffff809de6dc
stack pointer = 0x28:0xfffffe066064a7c0
frame pointer = 0x28:0xfffffe066064a840
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 885 (test)
