VLAT 2009  root@saturn:/usr/obj/sys/arch/i386/compile/GENERIC i386

hi all,
I've got the next problem...
kernel: supervisor trap protection fault, code=0
Stopped it pid 0.1 (swapper) at netbsd:Xintr_ioapic_edge14+0xe4: mov
Xinitr_ioapic_edge14() at netbsd:Xinitr_ioapic_edge14+0xe4
--- interrupt ----
Bad frame pointer: 0xc112fc98
Bad character
I implement a new software which is support hardware device in netbsd and got 
this kernel crash. I seems, what it befalls after accessing into pci-bus 
memory(my hardware without i\o ports) that new device, but attaching and 
opening occurred without any fails.
I find out this function in there.
456:#if NIOAPIC > 0
457:.globl _C_LABEL(ioapic_edge_stubs)
487:    .long _C_LABEL(Xintr_ioapic_edge14), _C_LABEL(Xrecurse_ioapic_edge14)
488:    .long _C_LABEL(Xresume_ioapic_edge14)
Possibly my opinion pertaining to memory access is wrong.
Suggest to me something, what can be help me to fixit.
thanks in advance.
