(Get the code!)
Not only does this hang, frequently; I also saw the following *wonderful* error message a few times:
Uhhuh. NMI received for unknown reason b1 on CPU 0.
You have some hardware problem, likely on the PCI bus.
Dazed and confused, but trying to continue.
Substituting tg3 for another driver (ThinkPad users have e1000 anyway) seems to still produce the hang - I had the pcmcia socket as a module and used that instead, that caused the hang.
Repeatedly loading tg3 and the pcmcia socket together does _not_ hang.
My hypothesis is that the iwl family of drivers may leave the PCI bus in an invalid state, so when combined with another driver load, can cause a hang or at least leaving the kernel severely unhappy.
