It is possible your motherboard vendor screwed up: http://developer.intel.com/design/support/faq/82559.htm Apparently, some motherboard vendors let boards go out with wrong wiring or capacitors (see the bottom of the page), and the symptoms match yours (which, I must stress, may very well be a coincidence). It is no doubt an oversight that this info is on the web site, seeing that the "errata" for the 8255x seem to be available under NDA only... And those errata make the difference between a reliable and an unreliable drivern (actually, I think the developers did have access to the errata; I see a workaround for at least one known issue with the 82559 in the if_fxp.c source). Incidentally, the 3Com 3C905TX is actually worse in this respect than the Intel 100Pro.
