Just to add a further data-point: I have a Dell OptiPlex GXi (Pentium-133 with 96MB RAM) that had 3 genuine PRO/100+ cards. It used to regularly lock up (to the point where NMI had no effect) under load (disk+network+CPU). Replacing the PRO/100+ associated with the multiplexed interrupt with a DEC DE500 (21143) solved the problem. I initially ran into the problem with 3.4-STABLE last February. I can't recall if I re-checked after I installed 4.x on the machine. I wound up switching to feeding all the relevant networks via a VLAN trunk into a single PRO/100+ and haven't had any problems since.
