Probem with Davicom91xx ethernet NIC on sparc64(v100/Netra-x) is well known (google ::dmfe+sparc). The problem is that specific driver (dmfe) can be loaded but once used couses errors on PCI/sabre and at the end couses Kernel Panic. Some pepole advice using (tulip) wich loads but fails to work normaly: it works at ~10Mbps in 10BaseT4 mode while all other modes brings huge amount of carierr/TX errors and VERY low throuput(sometimes 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 wich used on thoses machines. Usualy kernel unable to boot if strated without ide=nodma. If DMA set-on after boot is often couses data loses.
Bothe problems well known for a long time but somehow not treated till now. The problems exists in kernels since 2.4.17 up to latest 2.6.11 ( 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.
