Does anyone use a FDDI card on 5.0?

Still the same problem:

fpa0: <Digital DEFPA PCI FDDI Controller> port 0x10180-0x101ff mem
0x82030000-0x8203ffff,0x82041180-0x820411ff irq 3 at device 9.0 on pci0

unexpected machine check:

    mces    = 0x1
    vector  = 0x660
    param   = 0xfffffc0000006068
    pc      = 0xfffffc0000530d80
    ra      = 0xfffffc000039b51c
    curproc = 0xfffffc00005fdaf8
        pid = 0, comm = swapper

Stopped at      DELAY+0x50:     ldq
