Hi list,

After  an  upgrade  from  8.3  to  9.1-STABLE,  this  machine  started
crashing.

It's a GENERIC kernel with following changes:

options         DUMMYNET
options         IPFIREWALL
options         IPFIREWALL_FORWARD
options         IPFIREWALL_DEFAULT_TO_ACCEPT
options         HZ=1000

options         IPSTEALTH

options         IPFIREWALL_NAT
options         LIBALIAS
options         ROUTETABLES=16

Fatal trap 12: page fault while in kernel mode
cpuid = 3; apic id = 03
fault virtual address  = 0x0
fault code             = supervisor read data, page not present
instruction pointer    = 0x20:0xffffffff80956c73
stack pointer          = 0x28:0xffffff82ddbe3750
frame pointer          = 0x28:0xffffff82ddbe3760
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

Any ideas what might be wrong?

p.
