Well, it's vanilla 1.3 kernel, not current.
Unfortunately, I can't get the arguments of vm_fault() from crash dump.
(BTW - is it possible to dump a kernel core from ddb ?).
gdb has written this:

#0  0x6 in ?? ()
#1  0xf01c9747 in cpu_reboot (howto=256, bootstr=0x0)
    at ../../../../arch/i386/i386/machdep.c:1177
#2  0xf01264ad in panic (fmt=0xf01cd17a "trap")
    at ../../../../kern/subr_prf.c:150
#3  0xf01cd3d2 in trap (frame={tf_es = 16, tf_ds = 16, tf_edi = -559038737, 
      tf_esi = -192405896, tf_ebp = -192405888, tf_ebx = -259000576, 
      tf_edx = 30, tf_ecx = -259039104, tf_eax = -559038737, tf_trapno = 6, 
      tf_err = 0, tf_eip = -266572127, tf_cs = 8, tf_eflags = 66178, 
      tf_esp = -253895688, tf_ss = 120000, tf_vm86_es = 3, 
      tf_vm86_ds = -266275576, tf_vm86_fs = -259000576, 
      tf_vm86_gs = -192405860}) at ../../../../arch/i386/i386/trap.c:238


I'try to write down the arguments too next time this happens.
Should I find out some more info ?
