I've found the culprits.
it is CONFIG_MGEODE_LX.

If you configure your kernel with this cpu you got the interrupt problem:

 =======================

Do I missinterpret that the net5501 has a geode lx processor?
Any idea why this word with the pentium pro processor (CONFIG_M686) and not 
with the geode?
Anything else I've tested so far works perfect with the geode cpu flag.

Any ideas?
