I added a DEC DEFPA PCI FDDI card to my Alpha.
When ifconfig fpa0 <foo> I am greeted by the following
panic:
fatal kernel trap:
trap entry = 0x2 (memory management fault)
cpuid = 2
faulting va = 0x53c443f8000091b8

So, something appears to go wrong in:
static void
rt_maskedcopy(src, dst, netmask)
struct sockaddr *src, *dst, *netmask;
{
register u_char *cp1 = (u_char *)src;
register u_char *cp2 = (u_char *)dst;
register u_char *cp3 = (u_char *)netmask;
u_char *cplim = cp2 + *cp3;
u_char *cplim2 = cp2 + *cp1;
*cp2++ = *cp1++; *cp2++ = *cp1++; /* copies sa_len & sa_family */
cp3 += 2;
if (cplim > cplim2)
cplim = cplim2;
while (cp2 < cplim)
*cp2++ = *cp1++ & *cp3++;
if (cp2 < cplim2)
bzero((caddr_t)cp2, (unsigned)(cplim2 - cp2));
}
My other DEFPA lives in a BP6 x86 box and is not panicing.
Suggestions?
