It consists of: P-III 1,4 GHz Mainboard with SIS 630E chipset Adaptec 29160 Controller DLINK DFE-580 TX (four port card) (sundance driver) A slightly different setup is known to work with 2.4.19 and ACPI patch. Problem with this SIS chipset is interrupt sharing. If you do not use ACPI the box freezes sometime. The known-to-work setup is identical besides it contains a tulip-based four port ethernet card (old DLINK cards). We stress-tested the working box by NFS-copying data to the local hd over an ethernet port that shares its interrupt with the aic. The above failing setup with sundance driver results in network hanging, but no other negative points. The network hang can be cured by "mii-tool -r " (restart autonegotiation). After that everything works well, until the next hang. During the network hang the shared interrupt (aic + ethernet) still counts up. Maybe the sundance driver just misses an interrupt and hangs, and restarting autonegotiation resets some internals. I can try whatever patch you like, this is no production setup. Regards, Stephan
