I am using gigafar driver in linux kernel 2.6.13.4 version, but when I make the driver working, I start the samba function, and copy copy file from Windows PC to PPC system, when copy action starts, the events/0 occupy 40% CPU usage, while I using another system it is also linux 2.6.13, when copying file to system, events only occupy 1%, most of CPU loading are in network. Could some one tell me where is the optimization for that? Thanks. Best Wishes Jack Zhao USI SH R&D Center 86-021-58966996-1122
