I swapped my new SMC EtherPro 10/100 for an older one, so I've
gotten around the ROM problems with netbooting my AXPpci33. However,
I now seem to be having problems with the de driver itself. When
I netboot a June 16th kernel, it prints

    de0 at pci0 dev 12 function 0 at isa irq 5

    fatal kernel trap:

    trap entry = 0x2 (memory management fault)
    a0         = 0x0
    a1         = 0x1
    a2         = 0x0
    pc         = 0xfffffc000040ab90
    ra         = 0xfffffc000040f744
    curproc    = 0xfffffc000047e2e8
        pid = 0, comm = 

    panic: trap

Kgdb tells me this is:

(kgdb) l *(0xfffffc000040ab90)
0xfffffc000040ab90 is in tulip_2114x_media_preset (../../../../dev/pci/if_de.c:1474).
1469        if (media != TULIP_MEDIA_UNKNOWN) {
1470    #if defined(TULIP_DEBUG)
1471            if (media < TULIP_MEDIA_MAX && sc->tulip_mediums[media] != NULL) {
1472    #endif
1473                mi = sc->tulip_mediums[media];
1474                if (mi->mi_type == TULIP_MEDIAINFO_MII) {
1475                    sc->tulip_cmdmode |= TULIP_CMD_PORTSELECT;
1476                } else if (mi->mi_type == TULIP_MEDIAINFO_GPR
1477                           || mi->mi_type == TULIP_MEDIAINFO_SYM) {
1478                    sc->tulip_cmdmode &= ~TULIP_GPR_CMDBITS;

So I tried recompiling if_de.o with TULIP_DEBUG turned on, and
things got a little better:

    de0 at pci0 dev 12 function 0 at isa irq 5
    de0: preset: bad media 8!
    de0: SMC 9332DST 21140 [10-100Mb/s] pass 1.2
    de0: address 00:00:c0:39:1a:e4
    de0: enabling 10baseT port

However, when it tries to use de0 later:

    root device (default de0): 
    dump device: 
    file system (default nfs): 
    nfs_boot: using network interface 'de0'
    revarp failed, error=51
    cannot mount root, error = 5

and nothing ever appears on the net.

Any thoughts?
