Infact it is very likely the culprit. This is a 16-bit shared memory card, and you can not mix 8-bit and 16-bit memory access in the same 128K bios/shared memory area between 640K and 1M. For example, if you have an 8-bit BIOS at C800 you can't put a 16-bit shared memory card at CC00. The symptoms of doing this are exactly what you are getting. A hard reset will cure it, as that usually disables the shared memory on the SMC8013 until the driver turns it back on. > > I'll build a very recent kernel now to see if it's still there. > > --Chris Christoph P.
