It might even be a hardware failure (but I've tried with different cards of the same type, and all fail, while a Kingston Ne2000-clone works flawlessly). > > #4 0xf01b34ae in ed_pio_readmem (sc=0xf01ed400, src=25088, > > dst=0xefbfffc0 "'", amount=4) at machine/cpufunc.h:185 > > In my copy of cpufunc.h, line 185 is insb().
