That problem is VERY old and well known (google ::dmfe+sparc). The problem is that specific driver (dmfe) can be loaded but once used coses errors on PCI/sabre and at the end coses Kernel Panic. Some people advice using (tulip) which loads but fails to work normally: it works at ~10Mbps in 10BaseT4 mode while all other modes brings huge amount of carrier/TX errors and VERY low performance (usually less then 50Kbps) and after some time at mid/high load driver fails with some kind of TX errors. Another problem is with DMA on Alladin V which used on those machines. Usually kernel unable to boot if started without ide=nodma. If DMA set-on after boot is often coses data loses. Both problems well known for a long time but somehow not treated till now. The problems exists in all 2.4.x and 1.6.x kernels ( all versions in that range tested by me :-( ) I wonder if there anything that can be done to make those sparc64 machines usable with linux. Thanks ahead.
