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
